Detailed explanation-1: -Two ATP molecules are required to start glycolysis (from glucose), and four are generated by substrate-level phosphorylation. An additional two NADH molecules are generated, which can be used to generate another three to five ATP molecules through the electron transport chain in the mitochondria.
Detailed explanation-2: -Substrate-level phosphorylation is the production of ATP from ADP by a direct transfer of a high-energy phosphate group from a phosphorylated intermediate metabolic compound in an exergonic catabolic pathway.
Detailed explanation-3: -ATP is generated by substrate-level phosphorylation by high-energy compounds, such as 1, 3-bisphosphoglycerate and phosphoenolpyruvate. Glycolysis is used by all cells in the body for energy generation. The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions.
