Question

Choose the correct answers from the alternatives given :
During electron transport each molecule of NADH produces how many molecules of ATP?

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is C 3

During the electron transport system, NADPH produces 3 molecules of ATP while FADH${}_2$ produces 2 molecules of ATP by the process of oxidative phosphorylation because NADH gives its electrons to complex 1 which has the higher level of energy than the other complexes.

So, the correct option is ' 3'.
