It moves cyclically in cyclic photophosphorylation:
Correct answer: B. Electrons
- A. Oxygen
- B. Electrons
- C. ATP
- D. NADPH
Explanation
In cyclic photophosphorylation, electrons move cyclically through the electron transport chain of the thylakoid membrane. They are returned to the chlorophyll molecule, creating a cyclic flow that generates ATP. Oxygen is not involved in cyclic photophosphorylation. It is produced in non-cyclic photophosphorylation . ATP is produced during both cyclic and non-cyclic photophosphorylation. In cyclic photophosphorylation,NADPH is not produced in significant amounts in cyclic photophosphorylation. It is primarily generated in non-cyclic photophosphorylation.

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.
