The Mechanism of Photophosphorylation is Most Similar to Which of the Following

Question

The mechanism of photophosphorylation is most similar to which of the following processes?
A) substrate-level phosphorylation in glycolysis
B) oxidative phosphorylation in cellular respiration
C) the Calvin cycle
D) reduction of NADP+

Accepted Answer

Photophosphorylation in photosynthesis is similar to oxidative phosphorylation in cellular respiration as both involve the generation of ATP using a proton gradient across a membrane and ATP synthase.
