FADH₂ Is a Less Powerful Reducing Agent (Electron Donor) Than

FADH₂ is a less powerful reducing agent (electron donor) than NADH.What is the consequence of this in oxidative phosphorylation?

A) FADH₂ requires more steps than NADH does in electron transport to become oxidized.
B) The electrons from FADH₂ enter electron transport at a higher energy level than the electrons from NADH.
C) A molecule of FADH₂ is only capable of producing 2 molecules of ATP, while a molecule of NADH is capable of producing 3 molecules of ATP.
D) Oxidation of FADH₂ occurs in the cytoplasm of the cell, while oxidation of NADH occurs in the mitochondria.
E) FADH₂ can only donate 1 phosphate group to ATP, while NADH can donate 2 phosphate groups to ATP.
