Which of these is able to cross the inner mitochondrial membrane?

Question

Quizplus · Accepted Answer

Fatty acyl-carnitine is able to cross the inner mitochondrial membrane. It is formed from fatty acyl-CoA and carnitine by the enzyme carnitine palmitoyltransferase I (CPT1), which is located on the outer mitochondrial membrane. Fatty acyl-carnitine is then transported into the mitochondrial matrix by a carnitine-acylcarnitine translocase on the inner mitochondrial membrane. Once inside the matrix, the fatty acyl-carnitine is converted back to fatty acyl-CoA by the enzyme carnitine palmitoyltransferase II (CPT2), which is located on the inner mitochondrial membrane. Acetyl-CoA, fatty acyl-CoA, and malonyl-CoA are unable to cross the inner mitochondrial membrane.
