Substrate level phosphorylation in glycolysis is catalyzed by
assistant
The correct answer is  In the reaction, catalyzed by phosphoglycerate kinase, phosphate is transferred from 1,3-bisphosphoglycerate onto ADP, forming ATP (substrate-level phosphorylation) and 3-phosphoglycerate. The phosphate of phosphoenolpyruvate is transferred to ADP in another substrate-level phosphorylation catalyzed by pyruvate kinase to form two molecules of ATP per molecule of glucose oxidized.
