Quizplus · Accepted Answer

The light reactions generate ATP and NADPH that are utilized in the Calvin cycle to synthesize carbohydrates. The Calvin cycle, in turn, replenishes the ADP, Pi, and NADP+ required for the light reactions to continue generating ATP and NADPH. This cyclic process is crucial for the proper functioning of photosynthesis.
