MHT CET · BIOLOGY · STD 11 - 13. Respiration and Energy Transfer
During aerobic respiration, the total number of ATP formed through oxidative phosphorylation / ETS from one glucose molecule is ____.
- A thirty
- B thirty eight
- C eight
- D thirty four
Answer & Solution
Correct Answer
(B) thirty eight
Step-by-step Solution
Detailed explanation
The complete oxidation of glucose results in the production of 10 NADH molecules, which generate 30 ATP through oxidative phosphorylation, and 2 FADH2 molecules, which produce 4 ATP. Additionally, during glycolysis and the Krebs cycle, a net of 4 ATP molecules are formed through substrate-level phosphorylation. Thus, the total ATP yield is 30 +4+4=38 ATP.
