Fatty Acids Are Activated to Acyl-CoAs and the Acyl Group

Fatty acids are activated to acyl-CoAs and the acyl group is further transferred to carnitine because:

A) acyl-carnitines readily cross the mitochondrial inner membrane,but acyl-CoAs do not.
B) acyl-CoAs easily cross the mitochondrial membrane,but the fatty acids themselves will not.
C) carnitine is required to oxidize NAD⁺ to NADH.
D) fatty acids cannot be oxidized by FAD unless they are in the acyl-carnitine form.
E) None of the above is true.
