Question

Quizplus · Accepted Answer

In the light reactions of photosynthesis, the energy from eight photons of light is used to produce three molecules of ATP through the process of photophosphorylation. NADPH is produced through the transfer of electrons from water to NADP+ by the action of Photosystem II and Photosystem I. NADH is not produced in photosynthesis. Therefore, the correct choice is C, which states that three ATP are generated.
