What are the main products of the light reactions of photosynthesis?

Answer and explanation

Correct answer: D. ATP, NADPH and oxygen

  1. Step 1: The reactions occur in the thylakoid membranes. Step 2. Water is split to give oxygen, and energy is stored in ATP and NADPH. Answer: ATP, NADPH and oxygen. Why not the others: Glucose synthesis occurs in the stroma during light-independent Calvin cycle reactions, while photolysis of water molecules at photosystem II releases molecular oxygen during the light reactions.
