Out of 38 ATP molecules produced per molecule of glucose, 32 ATP molecules are formed from NADH/FADH2 in the
Respiratory chain
The electron transport chain along with oxidative phosphorylation involves the synthesis of energy-rich ATP molecules with the help of energy released during the oxidation of reduced coenzymes (NADH2 and FADH2) formed during glycolysis and the Krebs cycle. A total of 10 NADH2 and 2 FADH2 molecules are produced during aerobic respiration. They help in the formation of 32 ATP molecules.
