The light dependent reaction of photosynthesis occurs in:
Correct answer: C. Thylakoid membrane of chloroplast
- A. Stroma of chloroplast
- B. Guard cells of stomata
- C. Thylakoid membrane of chloroplast
- D. Cytoplasm of leaf cell
- E. None of the above
Explanation
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH. In plants, the light reactions take place in the thylakoid membranes of organelles called chloroplasts.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
