In Photosynthetic Cells,synthesis of ATP by the Chemiosmotic Mechanism Occurs

Question

In photosynthetic cells,synthesis of ATP by the chemiosmotic mechanism occurs during
A)photosynthesis only.
B)respiration only.
C)both photosynthesis and respiration.
D)neither photosynthesis nor respiration.
E)photorespiration only.

Accepted Answer

The chemiosmotic mechanism refers to the production of ATP through the generation of an electrochemical gradient across a membrane, which is driven by electron transport. This occurs during both photosynthesis (specifically, the light reactions) and respiration (specifically, oxidative phosphorylation). Therefore, choice C is correct. Choices A, B, D, and E are incorrect.
