The following is description of fatty acid (FA) metabolism. Which is correct?
Select one:
a. FA degradation is carried out by the repeated cycles of oxidation, hydration, oxidation, and deacetylation.
b. FA synthesis is carried out by the repeated cycles of acetylation, reduction, dehydration, and reduction
. c. Both A and B
d. Neither A nor B
Homework Answers
Answer:-
Fatty acids are broken down to acetyl-CoA by means of beta oxidation inside the mitochondria, whereas fatty acids are synthesized from acetyl-CoA outside the mitochondria, in the cytosol.
Hence, the correct option is (c) Both A and B.

Which of the following correctly compares fatty acid synthesis and fatty acid oxidation? Select ALL correct statements. Fatty acid synthesis requires reduced electron carriers while fatty acid oxidation requires oxidized electron carriers. Fatty acid synthesis and fatty acid oxidation both include a repeating cycle of reactions at some point during the process. Transport proteins in the mitochondrial membrane are required for fatty acid synthesis but not for fatty acid oxidation. Without metabolic coupling, fatty acid synthesis is an endergonic process...

Fatty Acid Metabolism. The reactions of the fatty acid spiral are shown below. Use the description on the left side of the page to classify the reactions and fill in the boxes on the right side of the page Activation Step. The activation of the fatty acid begins by the addition of CoA which will carry the fatty acid from the cytosol into the mitochondria. The product, which is a fatty acid with a CoA attached, is known as a...

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....

Complete the sentences to correctly describe steps in fatty acid synthesis. Put the terms to the appropriate blanks. Some terms will not be used, and some will be used more than once. Fatty acid synthesis begins with a preparatory step in which ____________ is transferred from ___________ to the ___________. However, it cannot pass through the membrane, so it is transported as ___________, which is cleaved to ____________ and ____________. In the cytosol, acetyl CoA is converted to ____________, a...
