Phosphoglycerate kinase is an enzyme that catalyzes a key step in glycolysis, specifically the conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate while transferring a phosphate group to ADP to form ATP. This enzyme plays a crucial role in the energy-yielding phase of glycolysis, contributing to the production of ATP that cells use for energy. Its activity is essential for the efficient metabolism of glucose and the overall energy balance within the cell.
