Question

Quizplus · Accepted Answer

The ATP produced in the citric acid cycle is generated by substrate-level phosphorylation, which involves the transfer of a phosphate group from a high-energy molecule to ADP to form ATP. This process occurs twice during the citric acid cycle, resulting in a net gain of 2 ATP molecules. Chemiosmosis, electron transport, photophosphorylation, and oxidative phosphorylation are all processes involved in ATP production in other cellular pathways, but not in the citric acid cycle.
