Explanation:
Detailed explanation-1: -Substrate-level phosphorylation is the direct formation of ATP or GTP by transferring a phosphate group from a high energy compound to an ADP or GDP molecule. There are two reactions in glycolysis that involve substrate-level phosphorylation.
Detailed explanation-2: -Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.
