Glycolysis preparatory phase -2 Phosphorylation of glucose and fructose 6-phosphate uses two ATP from the cytoplasm.
Glycolysis pay-off phase
4 Substrate-level phosphorylation
2 NADH 4Oxidative phosphorylation – Each NADH produces net 2 ATP due to NADH transport over the mitochondrial membrane
Oxidative decarboxylation of pyruvate
2 NADH 5 Oxidative phosphorylation
Krebs cycle
2 Substrate-level phosphorylation
6 NADH 15 Oxidative phosphorylation
2 FADH2 3 Oxidative phosphorylation
Total yield 31 ATPFrom the complete oxidation of one glucose molecule to carbon dioxide and oxidation of all the reduced coenzymes.
