How is Coenzyme A (cellular respiration) abbreviated? The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does. © 2003-2012 Princeton University, Farlex Inc. ... Aerobic Respiration. It unites with Coenzyme — A (CoA) and forms acetyl CoA (active acetate). C 6 H 12 O 6 + 6O 2 + 6H 2 O → 12H 2 O + 6 CO 2. If I have 12 NADH from glycolysis, what is the net ATP? Most students never learn….the ones who get good grades often just use diffrent memory-methods for remembering….While if you would have had the students speak spanish, french or german for that hour of class…they would all be somewhat fluent after a semestre of babbling. message for the sisters. In the process, energy in the form of a molecule called adenosine triphosphate, or ATP, is released.The function of coenzyme A in the citric acid cycle is most like. Okayy… This is the hardest one by far I’ve rewatched it like 3x and still need another 10x of rewatching it. AND YOU STILL DON’t UNDERSTAND, so your friend tutors you, AND YOU STILL DON’T UNDERSTAND. Coenzymes are often widely called cofactors, but they are chemically different.A coenzyme cannot work on its own, but it can be reused multiple times when combined with an enzyme.. Coenzyme functions I’m an older biology beginner here:-) Great video, but I think I will have to watch a few times! (2019, September 2). All Right Reserved. The All Mind is both relative and collective, micro and macro. Cellular respiration is a catabolic pathway in which glucose is completely oxidized, yielding CO 2 and the high-energy, reduced electron carriers NADH and FADH 2, and ATP. Aren’t the “Prep Steps” actually called Link Reaction and I learned that they were already separate from the Krebs Cycle. So I’m sitting here not moving my finger. (Thus, the Krebs Cycle is considered an aerobic process)\nReference Source: OpenStax https://cnx.org/contents/[email protected]:[email protected]/Oxidation-of-Pyruvate-and-the-\n\n36 ATP? ... Cellular respiration. It doesn’t directly use oxygen, though. in political science from State University of New York and a Master of Environmental Law and a J.D. I’m tripping on acid rn, just trying to understand why we personify cells and viruses as God and the Devil lmaoo. In the mitochondria the pyruvate (3 carbons) produced in glycolysis is converted to Acetyl Coenzyme A and CO2 by the pyruvate dehydrogenase enzyme complex. Cellular respiration in the absence of molecular oxygen is (a) photorespiration (b) glycolysis (c) EMP pathway (d) HMS pathway Answer: (b) glycolysis 2. The molecule acts as a shuttle for electrons during cellular respiration. Merhabalar YouTube kanalınızın para kazanması etkin ise satın almak istiyorum satmayı düşünürmüsünüz? Use of this web site constitutes acceptance of the LIVESTRONG.COM In biological systems, an important enzyme involved in the regulation of redox reactions is.Coenzyme. Cellular respiration is the process by which cells convert food energy like glucose into a form of energy that can be used to build and repair tissue and carry on other cell functions. Pyruvate oxidation and the citric acid cycle Pyruvate oxidation How pyruvate from glycolysis is converted to acetyl CoA so it can enter the citric acid cycle. Oral contraceptives might increase the need for pantothenic acid intake. Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. I’ve just found my new favorite YouTube channel ❤️. This process is an essential part of the cellular respiration cycle. In glycolysis , two NADH and two ATP are produced, as are two pyruvate. Hey I’ve got a question ✋I’ve seen it in my exams so many times and I haven’t gotten the right answer yetIs that ATP maker enzyme a part of the chain or a separate thing? I watched it right before a final and it really helped. In the process, each pyruvic acid molecule loses one carbon atom, which combines with available oxygen to produce carbon dioxide, which is released through exhaling. – Current A&P college student, you used the pedagogical method of dual coding so well to explain this; kudos and thanks a lot…also me at 07:43 O.o.:p. used as a substitute for professional medical advice, And here is me…in my country we study this in school. Fundamental statements for this Softchalk Lesson: 1. - [Voiceover] So what I wanna do in this video is give ourselves an overview of cellular respiration. Dietary sources of pantothenic acid include yogurt and milk, fish, chicken and eggs, lentils and peas, and yeast breads. Coenzyme A (CoA, CoASH, or HSCoA) is a coenzyme used in up to 4% of enzymatic reactions within all living cells. The product of this reaction is a two-carbon molecule called acetyl-CoA. https://www.khanacademy.org/science/biology/crash-course-bio-ecology/crash-course-biology-science/v/crash-course-biology-106\n\nAbout Khan Academy: Khan Academy is a nonprofit with a mission to provide a free, world-class education for anyone, anywhere. by Paul M. Insel, R. Elaine Turner, Don Ross, by John W. Erdman, Jr., Ian A. MacDonald, Steven H. Zeisel. Need a reviewer for an essay I wrote for extra credit, is this all correct? However, please remember that this is an education channel. We believe learners of all ages should have unlimited access to free educational content they can master at their own pace. Respiration is the reaction that produces the ATP needed for other metabolic reactions in cells. Responsibility disclaimer and privacy policy | Site Map, All about how to eat right, diet and exercise. In order for pyruvate, the product of glycolysis, to enter the next pathway, it must undergo several changes to become acetyl Coenzyme A (acetyl CoA). The citric acid cycle initiates with (a) succinic acid (b) pyruvic acid (c) acetyl coenzyme A (d) fumaric acid Answer: (c) acetyl coenzyme A 3. . How is it the insufficient/weak/mutated/excessive (I don’t think excessive is a possible reason for mitochondria) mitochondria does not come from the paternal side and the condition is link with the maternal? Its main function is to deliver the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production. Role of Enzymes in Cellular Respiration. The process generates a net profit of two ATP, plus some NADH and carbon dioxide.\n\nIn the Krebs Cycle within the mitochondrial matrix, the Acetyl CoA is added to Oxaloacetate in a cyclical set of reactions. The remaining carbon atoms bond with coenzyme A, creating acetyl CoA. As high-energy electrons delivered by NADH and FADH2 traverse the electron transport chain to oxygen, it produces ATP and water. Degradative reactions resulting in the formation of acetyl coenzyme … Holly shit the pneumonic caught me off guard. We should clarify the entire ATP hydrolysis process itself is considered an energy releasing, exergonic process. Click on "Watch later" to put videos here, In which Hank does some push-ups for science and describes the \”economy\” of cellular respiration and the various processes whereby our bodies store energy in the form of ATP. It includes glycolysis, the TCA cycle, and oxidative phosphorylation. Drag each compound to the appropriate bin. any of the products or services that are advertised on the web site. Cellular respiration refers to the breakdown of glucose and other respiratory substrates to make energy carrying molecules called ATP. from Vermont Law School. Cellular respiration consists of three related series of biochemical reactions: 1. NADH interacts with the electron transport chain by transferring electrons to (and thereby reducing) complex I that, in turn, reduces coenzyme Q (ubiquinone). III. Please note that there is a BLEEPED expletive included in the mnemonic at 7:38– 7:49 in the video. It is the process by which cellular metabolism begins converting glucose, the main fuel used by the body obtained from starches and sugars, into usable energy. Chapter 9 Vocabulary- Cellular Respiration 1. acetyl CoA-Acetyl coenzyme A; the entry compound for the citric acid cycle in cellular respiration, formed from a two-carbon fragment of pyruvate attached to a coenzyme. CC-BY. More hydrogen atoms are transferred to NAD during this reaction. Thanks so much for this video! Copyright Policy The material appearing on LIVESTRONG.COM is for educational use only. A fifth Complex Lets these hydrogen ions run back through, like water through a water wheel. The reduced coenzyme NADPH plays a key role in the Calvin cycle for the production of carbohydrates in photosynthetic organisms. Thanks for the help. An alternative is specifically suggested, but if you have delicate sensibilities, consider fast-forwarding for those 10 seconds! Why would the yeast in a bottle at room temperature with one teaspoon of sugar produce just as much carbon dioxide through cellular respiration than a heated bottle with no sugar in it? and Nicotinamide adenine dinucleotide, or NAD, also carries away hydrogen in the process of oxidation, becoming NADH. Specifically, the coenzyme ATP is a major player in moving energy within the cell. You deserve more subscribers. The citric acid cycle initiates with (a) succinic acid (b) pyruvic acid (c) acetyl coenzyme A (d) fumaric acid Answer: (c) acetyl coenzyme A 3. When in fact, your videos are more informative than others. But if I do more than just move my finger — say if I lift weights vigorously for 20 seconds — then the cells will use up all the oxygen available at some point and start creating lactic acid to create energy through an anaerobic (no oxygen) process. Coenzymes are often broadly called cofactors, but they are chemically different. Acetyl CoA has high potential energy making it a great resource to further cellular respiration. Cells use ATP or Adenosine Triphosphate as their energy currency, but where does it come from? In cellular respiration, glucose and other organic molecules are broken down in a series of steps Electrons from organic compounds are usually first transferred to NAD+, a coenzyme As an electron acceptor, NAD+ functions as an oxidizing agent during cellular respiration Each NADH (the reduced form of NAD+) represents Cellular respiration is the process by which cells convert food energy like glucose into a form of energy that can be used to build and repair tissue and carry on other cell functions. It is made to assist with revision and in preparation for cellular respiration. Acetyl-CoA (acetyl coenzyme A) is a molecule that participates in many biochemical reactions in protein, carbohydrate and lipid metabolism. Maybe my brain cells need to get up to speed with study again haha! CoA is defined as Coenzyme A (cellular respiration) very frequently. One question, though: Why do you say that the citric acid cycle requires oxygen? When you still don’t understand any biology and you’re bingeing all the crash course videos. [gluclose, ADP, ATP, O2, CO2, NAD, NADH, Coenzyme A, Pyruvate, acetyl CoA] An example is coenzyme A (CoA), which combines with a two-carbon compound during the link A nonprotein organic molecule that binds to an enzyme is active site, allowing the enzyme to function is called a _____ Yes, but only to a given point The vitamin _____ Is part of the coenzyme NAD which functions in cellular respiration. Take away two because of the initial two ATP spent doing glycolysis and one Glucose Molecule can be turned into 38 ATPs, We like to pin clarifications or corrections to our videos. I’m confused, so if Glycolysis yields 2 NADH and we have two pyruvate that yield 6 NADH through the Kreb’s cycle that would be 8 NADH, but Hank says 10 NADH for the electron transport chain, I think I lost track of the numbers, These people need more subscribers And get some other people to make a chemistry versionAs well as every other science in the worldThen the world would be perfect, I really love your videos. From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. As cellular respiration continues, the reduced carriers, NADH and FADH2, transfer the energy and electrons to the electron transport chain, helping to make ATP. Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis. From the following compounds involved in cellular respiration, choose those that are the net inputs and net outputs of glycolysis. Copyright © 2021 - NutritionOfPower.com. We offer free personalized SAT test prep in partnership with the test developer, the College Board. Video taken from the channel: Biology Bugbears, Part 3 in a 9 part lecture on CELLULAR RESPIRATION in a flipped General Biology course taught by Wendy Riggs. Glycolysis is the first step in cellular respiration. This is one of a series of videos on cellular respiration and photosynthesis. This also compares this process to photosynthesis and introduces ATP structure. Lactic acid doesn’t make you sore, it attributes to the burn in your muscles because it takes up space in your blood leaving less room for oxygen but the soreness is from the damage to the z lines in your muscles from eccentric contractions. The last step is to add coenzyme A (a sulfur containing atom).Coenzyme A is attached to the acetate by its sulfur atom. The NADHs that are produced before the Kreb’s cycle aren’t produced in the mitochondrial matrix, so how do they give rise to ATPs? We do wish we had been more clear stating that the Krebs cycle \”‘indirectly\” requires oxygen\” instead of just stating it \”requires oxygen\” —as we do not want to imply that oxygen is a reactant in the Krebs cycle (Citric Acid Cycle). Acetyl CoA acts as fuel for the citric acid cycle in the nest stage of cellular respiration. This BiologyWise post elaborates more on the function of NADH and FADH2. As a result, the rate of cellular respiration, and thus ATP production, decreases. My study resources list for science:Crash courseAmoeba sistersMaybe a little bit of that indian guy on youtube xD. This tutorial reviewed the first three stages of cellular respiration: glycolysis, pyruvate … The process is similar to burning, although it doesn’t produce light or intense heat as a campfire does. I had a small doubt:the immediate source of energy for metabolic reactions in a living cell is ____(is it glucose or atp). In electron transport chain you end up with the by-products carbon dioxide and water! Your email address will not be published. The molecule acts as a shuttle for electrons during cellular respiration. The Mystery of the Seven Deaths: A Case Study in Cellular Respiration Directions This activity is loosely based on the real-life 1982 Chicago Tylenol murders where seven people died when Tylenol capsules were laced with cyanide. It’s like he is guessing what he is saying and reading off a board!!! In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. In mitochondria, pyruvate will be transformed into a two-carbon acetyl group (by removing a m… What makes this possible at the cellular level? Your video’s are really helpful and deserve a lot more views, thanks! A coenzyme cannot function alone, but can be reused several times when paired with an enzyme.Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. Then after I’m done doing 4×8 90lbs dumbell bench presses, or 200 crunches, or skull crushers, etc. Cellular respiration is a complex metabolic pathway in which the glucose is broke down and get converted into an energy molecule (ATP).Cellular respiration is the process by which we can understand how a carbohydrate molecule is converted into an energy molecule in the form of ATP (Adenosine triphosphate) inside our body. How pyruvate from glycolysis is converted to acetyl CoA so it can enter the citric acid cycle. Drag each compound to the appropriate bin. (1) We received an excellent comment regarding the phosphate bond in ATP. Acetyl CoA has high potential energy making it a great resource to further cellular respiration. It is observed that during cellular respiration, every NADH molecule produces 3 ATP molecules, whereas each FADH2 molecule generates 2 ATP molecules. Next, The NADHs from the Krebs Cycle and Glycolysis along with the FADH2 molecules are deposited inside the Mitochondrial Matrix. I was just confused about where the protons come from to turn oxygen into water at the end of the Electron Transport Chain. (for the whole channel, pretty much), This is incredible!!! Free radical and law and order. We also reserve the right to remove comments with vulgar language.\n\nMusic is this video is listed free to use/no attribution required from the YouTube audio library https://www.youtube.com/audiolibrary/music?feature=blog\n\nWe have YouTube’s community contributed subtitles feature on to allow translations for different languages. So if i inhale deeply 30 times and exhale enough to relax will i generate a alkaline environment instead of lactic acid in my muscle by holding my breathe on the 30th exhale and waiting for my body to send oxygen through out my system then inhale after i do say 40 push ups I will not be sore! Fundamental statements for this learning object: 1. It is the process by which cellular metabolism begins converting glucose, the main fuel used by the body obtained from starches and sugars, into usable energy.1 decade ago. And regarding the video note about how ATP may need to be used to shuttle in NADH from glycolysis—here’s a question answered by Miller and Levine that you may find helpful: http://www.millerandlevine.com/ques/atp.html\n\nSupport us on Patreon! Coenzyme A is released once again back into the cell structure, while the two carbons that had rendered it an acetyl group join the four-carbon compound, turning it into a six=carbon compound. I’ve been trying to wrap my head around how cellular respiration worked (learning about metabolism) for THREE straight years. This creates an electrochemical gradient, meaning that those Hydrogen Ions want to get back into the Mitochondrial Matrix. There are a set of four Complexes along the inner membrane of the mitochondria that take two electrons from each NADH and each FADH2 and pump out a total of six hydrogen Ions into the Intermembrane space, the area between the inner and outer membranes of the mitochondria. Cellular respiration refers to the breakdown of glucose and other respiratory substrates to make energy carrying molecules called ATP. Nicotinamide Adenine Diphosphate (NAD) is a coenzyme that plays a central role in cellular respiration as it acts as a means of electron transport. ATP synthase: An enzyme that catalyses the synthesis of ATP in oxidative phosphorylation. The product of this reaction is a two-carbon molecule called acetyl-CoA. Required fields are marked *. Atheists are so dim. Coenzyme A, synthesized by the body from pantothenic acid, or vitamin B-5, plays a key role in aerobic cellular respiration. These reactions generate a few more ATP plus a load of NADH and FADH2.\n\nFinally, the Electron Transport Chain creates a proton gradient across the membrane separating the mitochondrial matrix from the intermembrane space. At various chemical reactions, the NAD+ picks up an electron from glucose, at which point it becomes NADH. Left … It was discovered by Hans Kerbs. 38 ATP? This process is an essential part of the cellular respiration cycle. Cellular respiration definition, the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Hydrocephalus does not necessarily cause any disabilities or developmental delays if caught and treated early. The molecule consists of two nucleotide units where one contains adenine as the nucleobase, and the other contains the nicotinamide unit. 2. alcohol fermentation-Glycolysis followed by the reduction of pyruvate to ethyl alcohol, regenerating NAD + and releasing carbon dioxide.3. of a cell’s ATP is made during respiration. If the compound is not involved in glycolysis, drag it to the "not input or output" bin. The last step is to add coenzyme A (a sulfur containing atom).Coenzyme A is attached to the acetate by its sulfur atom. As far as I know the soreness is not the lactic acid but rather microscopic tears in the fibers and the resulting inflammation. The Crash Course guy also says the citric acid cycle needs oxygen and I don’t know where this idea came from…. Pyruvate oxidation converts pyruvates - a three-carbon molecule- into CoA (acetyl) a two-carbon molecule attached to coenzyme A- producing NADH and releasing one carbon dioxide molecule in the process. ADP gained an electron and become ATP alone in glycolysis. A freelance writer since 1978 and attorney since 1981, Cindy Hill has won awards for articles on organic agriculture and wild foods, and has published widely in the areas of law, public policy, local foods and gardening. ... which stands for coenzyme A. In this video, the specific stages of cellular respiration will be described. The few known information I’ve seen states mitochondria comes from the maternal side (I am not sure if they are referring to the condition, disease?) This is a summary very simple video covering details on NADH for my classes. It is linked to mitochondrial ROS production and detoxification, generation of electrochemical gradients across membranes, thermogenesis, and oxidative phosphorylation. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/biology\n\nWe take pride in our AWESOME community, and we welcome feedback and discussion. It is thus part of the aerobic respiratory chain of the cell, and its primary function may be maintenance of the [NADH]/[NAD+] balance of the cell. CoA stands for Coenzyme A (cellular respiration). While oxygen is not a reactant for the Krebs Cycle, the oxidation steps of the Krebs Cycle cannot occur without the presence of oxygen. This and Photosynthesis are the two things I need to get figure out before the exam tomowrow. She holds a B.A. Good for you Crash Course! The equation of cellular respiration helps in calculating the release of energy by breaking down glucose in the presence of oxygen in a cell. Transition Reaction. Why not break the two other phosphates to get 2 more electrons? Aerobic respiration has four stages: Glycolysis, formation of acetyl coenzyme A, the citric acid cycle, and the electron transport chain.Cells of all living organisms need NADH and FADH2 (naturally occurring coenzymes) for energy production. \n\nFor free. A child’s chromosome (DNA) comes from the half paternal and half maternal. This is a question I struggled with in AP. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds. there’s something I don’t get though. The figures below illustrate the similarities between ATP synthesis in mitochondria and chloroplasts. Coenzymes are often widely called cofactors, but they are chemically different. Oxygen functions as the final electron acceptor to absorb the electrons that are exiting the Electron Transport Chain.\n\nAvoid plagiarism! Lol either I have been watching too many crash course videos but he seems to be talking funny in this video unlike his other videos.. is it just me? However, as a result of the work of Warburg and his group, these coenzymes have been found to be true carriers Cellular Respiration 49 -- C-- C--A-- CH~-- OXIDIZED/COENZYME H-C The oxidized Coenzyme I has one less hydrogen atom and one less electron than the reduced Coenzyme I. After truly trying to pay attention to all of that, I still don’t really have a clue how chemical energy is transformed into the kinetic energy required to perform work (lifting weights, running, etc). Use of vulgar language and connotations about half way through. http://www.patreon.com/amoebasisters\n\nOur FREE resources:\nGIFs: http://www.amoebasisters.com/gifs.html\nHandouts: http://www.amoebasisters.com/handouts.html\nComics: http://www.amoebasisters.com/parameciumparlorcomics\n\nConnect with us!\nWebsite: http://www.AmoebaSisters.com\nTwitter: http://www.twitter.com/AmoebaSisters\nFacebook: http://www.facebook.com/AmoebaSisters\nTumblr: http://www.amoebasisters.tumblr.com\nPinterest: http://www.pinterest.com/AmoebaSister­s\nInstagram: https://www.instagram.com/amoebasistersofficial/\n\nVisit our Redbubble store at http://www.amoebasisters.com/store.html\n\nThe Amoeba Sisters videos demystify science with humor and relevance. It is the process by which cellular metabolism begins converting glucose, the main fuel used by the body obtained from starches and sugars, into usable energy. It really doesn’t. See YouTube’s community guidelines https://www.youtube.com/yt/policyandsafety/communityguidelines.html and YouTube’s policy center https://support.google.com/youtube/topic/2676378?hl=en\u0026ref_topic=6151248. As previously indicated, cellular respiration allows controlled release of free energy from carbohydrate, fat, and protein energy substrate. I really I understand all our lessons because of you. The reduced coenzyme NADPH plays a key role in the Calvin cycle for the production of carbohydrates in photosynthetic organisms. Of course the act of moving my finger won’t cause soreness in the muscles required to do so. If the compound is not involved in glycolysis, drag it to the "not input or output" bin. Coenzyme A, synthesized by the body from pantothenic acid, or vitamin B-5, plays a key role in aerobic cellular respiration. The only time I ever feel any range of soreness is when I’m done doing cardio – in which I inevitably go through anerobic respiration because My lungs can’t keep up. Photosynthesis is just a process of making food but this food is only utilized when the respiration process comes into play for the production of ATP molecules, for energy purposes? Copy and Paste the Following APA Citation:\n\n[BOGObiology]. Coenzyme that transfers electrons from the Krebs cycle to the mitochondrial electron-transport chain at a lower energy level than that of electrons entering at the beginning of the chain. For more information about The Amoeba Sisters, visit: http://www.amoebasisters.com/about-us.html\n\nWe cover the basics in biology concepts at the secondary level. by Anthony Strelkauskas, Angela Edwards, et. I got so scared not used to teachers saying things like that!!! al. Cellular respiration is the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes. As high-energy electrons delivered by NADH and FADH, traverse the electron transport chain to oxygen, it produces ATP and water. Turn that Alpha lamp on. Great video! Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis. During cellular respiration, the cells use these coenzymes to turn fuel from food into energy. Some other helpful things to note that were not explicitly stated in the video:-The Krebs Cycle occurs in the inside of the inner mitochondrial membrane AKA in the mitochondrial matrix. By doing so, acetyl CoA is formed. D. Cellular Respiration. Thanks amoeba sisters! My general understanding is the body is not able to store & metabolize protein. Without coenzymes or … Apparently after reading comments… I realised that you guys are being taught this stuff in collage…. How’d they get to the NAD/FAD bus stop in the first place? -Another name for the Krebs Cycle/Citric Acid Cycle is the Tricarboxylic Acid (TCA) Cycle, so if you ever hear those terms, know that they all refer to the same process.-Cellular respiration occurs not only in animal cells but also in plant cells. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. So while we- and many biology sources- mention the ATP bond breakdown as an energy releasing event, this can lead to a misconception if just isolating the phosphate bond breaking alone. Thank you so much!! I love you! NAD+, short for nicotinamide adenine dinculeotide, is a coenzyme that functions as an electron carrier in oxidation-reduction (redox) reactions in cells. Adenosine Triphosphate = gives 1 electron => Adenosine Diphosphate = gives 1 electron => Adenosine Phosphate = gives 1 electron = Adenosine. Cellular respiration is the process by which cells convert food energy like glucose into a form of energy that can be used to build and repair tissue and carry on other cell functions. Just–where did they come from? What is the reason behind NAD become only NADH but FAD become FADH2 why not FADH only or why not NADH2? Cellular respiration does not oxidize glucose in a single step that transfers all the hydrogen in the fuel to oxygen at one time. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
