What is the role of water in the light reactions of photosynthesis?

Question

Quizplus · Accepted Answer

Water is the source of electrons in the light reactions of photosynthesis. This is because during the light reactions, light energy is absorbed by pigments present in the thylakoid membrane of chloroplasts. This energy is then used to split water molecules into oxygen, protons (H+), and electrons. The electrons are then used to generate ATP and NADPH, which are used in the Calvin cycle to produce glucose.
