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
Homework Answers
The option is B
The amount of acyl carnitinine in the mitochondria regulates the fate of this acyl CoA
This is because carnitinine conjugation decreases the Number of acyl residues attached to COA

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. Explain the processes by which fatty acids are released from triacylglycerol stored in adipose tissue. 3. Outline the β-oxidation pathway by which fatty acids are metabolized to acetyl-CoA and explain how this leads to the production of large...

What changes in fatty acid metabolism would result from a mutation in the muscle carnitine acyltransferase I in which the mutant protein has lost its affinity for malonyl-CoA but not its catalytic activity? A. Fatty acid synthesis in the mitochondria and fatty acid oxidation in the cytosol could occur simultaneously. B. Fatty acid synthesis in the cytosol and fatty acid oxidation in the mitochondria could occur simultaneously. C. Synthesis of malonyl carnitine could only occur at high malonyl-CoA concentration. D....

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?

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.
