Which type of phosphorylation does not require a membrane?

Question

Quizplus · Accepted Answer

Substrate-level phosphorylation occurs when a phosphate group is transferred from a substrate molecule to ADP to form ATP, directly within the cytoplasm, without the need for a membrane-bound electron transport chain. This process is common in glycolysis and the citric acid cycle, where enzymes transfer phosphate groups to ADP. On the other hand, oxidative phosphorylation and photophosphorylation require membranes for electron transport and ATP synthesis. Therefore, Choice A is the correct answer.
