Question

photophosphorylation in photosynthesis is most similar to which of the following processes associated with cellular respiration? substrate - level phosphorylation in glycolysis pyruvate oxidation in the production of acetyl - coa oxidation of nadh in anaerobic fermentation oxidative phosphorylation in mitochondria

Explanation:

Photophosphorylation in photosynthesis involves the use of a proton gradient to generate ATP, similar to how oxidative phosphorylation in mitochondria uses a proton gradient (created by the electron - transport chain) to produce ATP. Substrate - level phosphorylation in glycolysis directly transfers a phosphate group from a substrate to ADP. Pyruvate oxidation mainly prepares pyruvate for the citric acid cycle. Oxidation of NADH in anaerobic fermentation is about regenerating NAD+ for glycolysis to continue.

Answer:

oxidative phosphorylation in mitochondria
