In aerobic respiration, total number of ATP molecules formed from 1 glucose molecule is
Options
- A28
- B32
- C36
- D30
Correct answer
C. 36
Step-by-step solution
The net gain from complete oxidation of a glucose molecule in aerobic respiration is 36 ATP molecules. 10 molecules of NADH ₂ ( 2 from Glycolysis +8 from Krebs' cycle) yield =10 3=30 ATP , 2 molecules of FADH ₂ yield =2 2=4 ATP and glycolysis also yields 2 ATP. Therefore, total release of ATP per hexose will be =30+4+2=36 ATP.
