Answer:
38 ATP
Step-by-step explanation:
One molecule of glucose on complete breakdown yields 38 ATP. The break up of APT production at different steps of cellular respiration is given below:
- Glycolysis yields 4 ATP and 2 NADH is produced, but 2ATP is used. Net gain of 2ATP.
- During formation of Acetyl CoA, 2 NADH is produced.
- During Krebs cycle 2 ATP, 6 NADH, 2 FADH₂ are produced.
- During Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP.
Each NADH releases 3 ATP and each FADH₂ releases 2 ATP. Altogether 10 NADH is produced which yield 30 ATP and 2 FADH₂ yields 4 ATP.
Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
