Detailed explanation-1: -ATP produced during glycolysis is a result of substrate level phosphorylation.
Detailed explanation-2: -Substrates like hexoses, pentoses, and glycerol, that require net flux through a version of glycolysis, will generate ATP via SLP.
Detailed explanation-3: -Answer and Explanation: The ATP made during glycolysis is generated by substrate level phosphorylation. This occurs twice in glycolysis. First off, when 1, 3-biphosphoglycerate is dephosphorylated by phosphoglycerate kinase the phosphate group is transferred onto adenosine diphosphate (ADP) to generate ATP.
Detailed explanation-4: -ATP is consumed for energy in processes including ion transport, muscle contraction, nerve impulse propagation, substrate phosphorylation, and chemical synthesis.
Detailed explanation-5: -Substrate-level phosphorylation occurs in the cytoplasm of cells (glycolysis) and in the mitochondria (Krebs cycle). It can occur under both aerobic and anaerobic conditions and provides a quicker, but less efficient source of ATP compared to oxidative phosphorylation.
