Quizplus · Accepted Answer

3-phosphoglycerate kinase is used in both glycolysis and gluconeogenesis. In glycolysis, it catalyzes the transfer of a phosphate group from 1,3-bisphosphoglycerate to ADP, forming ATP and 3-phosphoglycerate. In gluconeogenesis, the reaction is reversed, contributing to the synthesis of glucose from smaller precursors.
