試題詳解

10. In β-oxidation, long-chain fatty acids are activated to acyl-CoAs and the acyl group is further transferred to carnitine because:
(A) Fatty acids can not be oxidized by acyl-CoA dehydrogenase unless they are in the acyl-carnitine form.
(B) Acyl-CoAs easily cross the mitochondrial membrane, but the fatty acids themselves will not.
(C) Carnitine is required to oxidize to NADH.
(D) Acyl-carnitines readily cross the mitochondrial inner membrane, but acyl-CoAs do not.
