Substrate-level phosphorylation is a process that occurs during glycolysis and the citric acid cycle, where a phosphate group is directly transferred from a substrate molecule to ADP, forming ATP.
Identify the substrate molecule that carries the high-energy phosphate group. In glycolysis, this could be 1,3-bisphosphoglycerate or phosphoenolpyruvate.
The enzyme catalyzing this reaction facilitates the transfer of the phosphate group from the substrate to ADP, resulting in the formation of ATP.
Understand that this process does not involve the electron transport chain or oxidative phosphorylation, which are other methods of ATP production.
Recognize that substrate-level phosphorylation is a direct method of ATP synthesis, contrasting with oxidative phosphorylation, which involves a series of redox reactions and a proton gradient.
