What are the primary products generated by the light-dependent reactions of photosynthesis that drive the Calvin cycle?

Answer and explanation

Correct answer: C. ATP and NADPH

  1. Step 1: Non-cyclic photophosphorylation channels electrons through photosystems II and I. Step 2. Photolysis releases O2 while chemical energy is trapped as ATP and reducing power as NADPH, which are both consumed in the Calvin cycle. Answer: ATP and NADPH. Why not the others: Glucose is formed in the dark reactions; ADP and NADP+ are oxidized products returned to light reactions; CO2 and water are reactants.
