WebSubstrate-level phosphorylation occurs in the cytoplasm of cells during glycolysis and in mitochondria either during the Krebs cycle or by MTHFD1L ( EC 6.3.4.3 ), an enzyme interconverting ADP + phosphate + 10-formyltetrahydrofolate to ATP + formate + tetrahydrofolate (reversibly), under both aerobic and anaerobic conditions. WebThe oxidative phosphorylation is the major pathway by which energy is obtained in the form of ATP using various fuels. Electron transport chain (ETC) is a series of enzyme complexes that organized in an order of decreasing reducing power. It is present on the inner mitochondrial membrane and is a major source of ATP synthesis in animal cells. theo\u0027s melrose menuWebA-level Biology – The Krebs Cycle Products of Krebs Cycle The reduced NAD and reduced FAD produced in the link reaction and Kreb Cycle are important for the final stage – oxidative phosphorylation.
