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
Explanation
The correct answer is the thylakoid membrane of the chloroplast. The light-dependent reactions of photosynthesis occur in these membranes, where chlorophyll absorbs light energy. This energy is then converted into chemical energy in the form of ATP and NADPH, which are essential for the subsequent light-independent reactions (Calvin cycle) in the stroma.

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.
