What statement best explains why more ATP is made per molecule of NADH than per molecule of FADH2?

Net Input: Acetyl coenzyme A, NAD⁺, ADP
New Output: Coenzyme A, CO₂, NADH, ATP
Not Input or Output: Pyruvate, Glucose, O₂
In the citric acid cycle, the two carbons from the acetyl group of acetyl CoA are oxidized to two molecules of CO2, while several molecules of NAD+ are reduced to NADH and one molecule of FAD is reduced to FADH2. In addition, one molecule of ATP is produced.

Why is more ATP made per molecule of NADH than FADH2?

FADH2 produces less ATP then NADH because the electrons for FADH2 are dropped off at the second protein of the electron transport chain. FADH2 produces less ATP then NADH because NADH has more energetic electrons.

Why does NADH produce more ATP than FADH2 quizlet?

FADH2 produces fewer ATP molecules than NADH when it passes its electrons down the electron transport chain because FADH2 only activates 2 proton pumps, while NADH activates 3 proton pumps.

Why does NADH produce 3 ATP and FADH2 produce 2?

The oxidation of one molecule of NADH thus leads to the synthesis of three molecules of ATP, whereas the oxidation of FADH2, which enters the electron transport chain at complex II, yields only two ATP molecules.

Which statement best explains why FADH2 yields less ATP per molecule than NADH in oxidative phosphorylation?

Which statement BEST explains why FADH2 yields less ATP per molecule than NADH in oxidative phosphorylation? FADH2 is unable to activate any proton pumps in the ETC.
