question 35

Multiple Choice

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.
