Making Food “From Thin Air” You’ve learned that the first, light-dependent stage of photosynthesis uses two of the three reactants, water and light, and produces one of the products, oxygen gas (a waste product of this process). As shown in these two figures, the Krebs cycle and the Calvin cycle have some general similarities. C) both the light reactions and the Calvin cycle. The Calvin Cycle, named for Berkeley biochemist Melvin Calvin (1911-1997), the recipient of the 1961 Nobel Prize in Chemistry for discovering the Dark Reaction stage, is the process by which the plant makes sugar with the help of NADPH and ATP from the light reaction stage. It happens after the light-dependent reactions in photosynthesis. If both are present then the Calvin cycle can occur even at night. The Calvin cycle is named after Melvin C.
