On complete oxidation of one molecule of glucose yields 38 ATP. Break up of energy production is given below:
During glycolysis 2 ATP and 2 NADH is produced.
During formation of Acetyl CoA, 2 NADH is produced.
During Citric Acid Cycle, 2 ATP, 6 NADH, 2 FADH₂ are produced.
Finally during Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP. Each NADH produce 3ATP and each FADH₂ produces 2 ATP. Altogether 10 NADH is produced during entire process of cellular respiration which yield 30 ATP and 2 FADH₂ yields 4 ATP. Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
