Question

In the light reactions of photosynthesis, ATP is produced by photophosphorylation. Which of the listed processes is most similar to photophosphorylation?

-Oxidative phosphorylation in cellular respiration
-Glycolysis
-Citric acid cycle
-Carbon fixation
-Photorespiration
-Calvin cycle

Answer 1

Photophosphorylation in the light reactions of photosynthesis, which produces ATP, is most similar to oxidative phosphorylation in cellular respiration.

Step-by-step explanation:

Photophosphorylation is a process in the light reactions of photosynthesis where ATP is produced. This process is most similar to oxidative phosphorylation in cellular respiration, as both involve the production of ATP through chemiosmosis. In oxidative phosphorylation, ATP is generated in the mitochondria, while in photophosphorylation it occurs in the thylakoid membranes of chloroplasts.
