The rate limiting factor in the Ī²-oxidation of fatty acids in the mitochondria is Question 7 options: transport of fatty acids into the mitochondrial matrix cytoplasmic NADH levels the cytoplasmic ATP/ADP ratio inhibition of Acyl-CoA dehydrogenase by citrate
Added by Keith H.
Step 1
Ī²-oxidation is the metabolic process by which fatty acids are broken down in the mitochondria to generate acetyl-CoA, which can then enter the citric acid cycle for energy production. Show moreā¦

An activated fatty acid (acyl-CoA) can be transported into the mitochondria for Ī²-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

Which of the following is true about the regulation of fatty acid oxidation? Answers A - E High levels of acetyl CoA inhibits the activity of thiolase. Increased consumption of glucose stimulates fatty acid oxidation. Malonyl CoA activates carnitine acyl transferase I. Carnitine acyl transferase I is inhibited by acetyl CoA. High levels of NADH activate Ī²-hydroxyl CoA dehydrogenase.
