Photophosphorylation takes place in the _ of the chloroplasts:
Correct answer: B. Granum
- A. Stroma
- B. Granum
- C. Inner membrane
- D. Outer membrane
Explanation
Photophosphorylation takes place in the thylakoid membrane of the chloroplasts. This process, part of the light-dependent reactions of photosynthesis, uses light energy to create a proton gradient across the thylakoid membrane, which then drives the synthesis of ATP from ADP and inorganic phosphate.

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.
