Question

Quizplus · Accepted Answer

This reaction involves the direct transfer of a phosphate group from phosphoenolpyruvate to ADP, resulting in the synthesis of ATP. This is an example of ATP synthesis by substrate-level phosphorylation, which occurs when a high-energy phosphate group is transferred directly from a phosphorylated intermediate molecule to ADP.
