In the light reactions of photosynthesis, ATP is produced by photophosphorylation. However when the sun goes down. The potential of NADH and FADH 2 is converted to more ATP through an electron transport chain with oxygen and protons (hydrogen) as the "terminal electron acceptors". The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration. First Law of Thermodynamics introduction. During photosynthesis 18 molecules of ATP are used in c3 plants. Then, where does light reaction take place? The ATP and electron carriers are then used in a second set of reactions, called the light-independent reactions. anaerobic respiration Respiration! Four major protein complexes are located in the thylakoid membrane: Photosystem II (PSII), Cytochrome b6f complex, Photosystem I (PSI), and ATP synthase that works together in carrying out the light reaction in plants.
