Substrate-level phosphorylation involves the transfer of a phosphate group from a high-energy substrate molecule to ADP to form ATP. Enzymes such as pyruvate kinase and phosphoglycerate kinase are involved in this process. These enzymes catalyze reactions where a phosphate group is directly transferred to ADP, bypassing the need for the electron transport chain.
