Question

(BIOCHEMISTRY QUESTION) NADH produces 2.5 ATP whereas FADH2 produces only 1.5 ATP. Which of the following can reconcile this difference?

a. NADH transfers two electrons to the electron transport chain whereas FADHS only transfers one

b. NADJ transfers electrons to coenzyme Q through complex I a process that translocates four protons. FADH2 however transfers electrons to complex II which only translocates two protons

c. the reduction potential of NADH is lower than the reduction potential of FADH2

d. none of the above

Explanation / Answer

The option C is right, i.e., the reduction potential of NADH is lower than the reduction potential of FADH2.
