Fatty acids are activated on the outer membrane of the mitochondria. This reaction involves the addition of a CoA group to the fatty acid (to generate an Acyl CoA), and the hydrolysis of ATP to AMP. After fatty acids are activated, they must be linked to carnitine for transport across the inner mitochondrial membrane. Then, how many carbons are oxidized at a time? What molecules are generated by fatty acid oxidation?
Homework Answers
Two carbons are oxidized at a time and the molecules generated by fatty acid oxidation are called acetyl-CoA.

An activated fatty acid (acyl-CoA) can be transported into the mitochondria for b-oxidation or remain in the cytosol for lipogenesis to produce a triacylglycerol. What regulates the fate of this acyl-CoA? A. the amount of acyl-CoA in the mitochondria B. the amount of acyl-carnitine in the mitochondria C. the amount of NADH in the cytoplasm D. the amount of malonyl CoA in the cytoplasm E. the amount of acetyl-CoA in the cytoplasm

Fatty acid oxidation occurs in the mitochondrial matrix. However, long-chain fatty acyl-CoA molecules cannot cross the inner membrane to enter the matrix. The carnitine shuttle system transfers the acyl group from CoA to carnitine, which can enter the mitochondrial matrix.
Label the enzymes and compounds of the carnitine shuttle system. The following enzyme abbreviations are used: carnitine acyltransferase I, CAT1; mitochondrial carnitine acyltransferase II, CAT2; and carnitine/acylcarnitine translocase (carnitine carrier protein), CAT.

1. Describe the processes by which fatty acids are transported in the blood, activated and transported into the matrix of the mitochondria for breakdown to obtain energy. (Specifically, determine the role of carnitine palmitoyl transferase in the oxidation of fatty acids.) 2.

Outline the β-oxidation pathway by which fatty acids are metabolized to acetyl-CoA and explain how this leads to the production of large...
SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids?...
SELECT ALL THAT IS/ARE CORRECT: Why is the carnitine shuttle necessary for oxidation of fatty acids? A.Because the lipid bilayer may confuse the incoming fatty acids as part of the membrane. Without the carnitine shuttle, the lipid bilayer may incorporate the fatty acids into the membrane instead of breaking it down via oxidation. B.Because fatty acids cannot directly pass through the mitochondrial membranes. C.Because fatty acids must be "tenderized" - i.e., multiple functional groups are added in order to facilitate...
