The First Three Reactions of the β-Oxidation Cycle of Fatty

Question

The first three reactions of the β-oxidation cycle of fatty acids produce
A) two moles of NADH
B) two moles of FADH2
C) one mole each of NADH and FADH2
D) two moles of ATP

Accepted Answer

The first three reactions of the β-oxidation cycle produce one mole of NADH and one mole of FADH2 for each acetyl-CoA molecule produced. Therefore, the correct choice is C, one mole each of NADH and FADH2. Option A is incorrect since it mentions two moles of NADH while the first three reactions produce only one mole. Option B is incorrect as it is not a valid chemical compound. Option D is incorrect since ATP is not produced during the first three reactions, but rather during the subsequent steps of the cycle.
