Aerobic respiration of glucose produces ATP. How many of them are produced during electron transport system?
Options
- A32
- B34
- C28
- D2
Correct answer
B. 34
Step-by-step solution
Electron transport system is responsible for oxidation of reduced coenzymes. 1 NADH passes through ETS to release 3 ATP while 1 F A D H 2 passes through ETS to release 2 ATP. One molecule of glucose produces 10 NADH (2 from Glycolysis, 2 from link reaction and 6 from Krebs cycle). Thus 30 ATPs will be formed from them. One molecule of glucose also produces 2 F A D H 2 from Krebs cycle. Thus 4 ATPs will be formed from them. Thus total ATP produced from ETS is 34
