The following is/are obtained during cyclic photophosphorylation:
Correct answer: A. ATP
- A. ATP
- B. NADPH2
- C. O2
- D. All of these
Explanation
In cyclic photophosphorylation, electrons released by chlorophyll return to the same chlorophyll molecule, and ATP is produced. This process occurs in the thylakoid membranes and is part of the light-dependent reactions of photosynthesis. Unlike non-cyclic photophosphorylation, cyclic photophosphorylation does not produce NADPH₂ or oxygen (O₂), as there is no photolysis of water involved. Therefore, the correct answer is Option A: ATP.

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.
