Question

For each NADH molecule that moves through the electron transport system, what is the potential yield of ATP molecules?

A) 1
B) 2
C) 2.5
D) 3.5
E) 4

Answer 1

For each NADH molecule that goes through the electron transport system, approximately 3 ATP molecules are produced as a result of oxidative phosphorylation.

Step-by-step explanation:

For each NADH molecule that moves through the electron transport system (ETC), the potential yield of ATP molecules is approximately 3. This is due to NADH entering the ETC at Complex I, which has a high transfer potential, leading to the generation of a significant proton motive force capable of producing roughly three ATP molecules through oxidative phosphorylation.
