Enzymes for the light-dependent reactions are present in:
Correct answer: B. Thylakoid membrane of the chloroplast
- A. Mitochondria
- B. Thylakoid membrane of the chloroplast
- C. Stroma of the chloroplast
- D. Cytoplasm of the cell
Explanation
The light-dependent reactions of photosynthesis take place within the thylakoids. These reactions occur when the pigment chlorophyll, located within the thylakoid membranes, captures energy from the sun (photons) to initiate the breakdown of water molecules.

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.
