Photophosphorylation in photosynthesis is most similar to which of the following processes associated with cellular respiration?
A)substrate-level phosphorylation in glycolysis
B)pyruvate oxidation in the production of acetyl-CoA
C)oxidation of NADH in anerobic fermentation
D)oxidative phosphorylation in mitochondria

Question

Quizplus · Accepted Answer

Photophosphorylation in photosynthesis and oxidative phosphorylation in mitochondria both involve the generation of ATP via an electron transport chain and chemiosmosis. Both processes utilize a proton gradient across a membrane to drive the synthesis of ATP by ATP synthase. Substrate-level phosphorylation in glycolysis and pyruvate oxidation in the production of acetyl-CoA involve the direct transfer of a phosphate group to ADP to generate ATP, while oxidation of NADH in anaerobic fermentation does not involve the generation of ATP at all.
