Question

How does the structure of fatty acid synthase differ from that of the enzymes that carry out beta-oxidation? Fatty acid synthase is found in the mitochondrial matrix space. Fatty acid synthase is found in the cytoplasm. Fatty acid synthase is composed of seven enzymes that are not physically associated another. beta-oxidation enzymes are found in the mitochondrial matrix space. Fatty acid synthase is a huge multienzyme complex composed of seven enzymes. beta-oxidation enzymes are found in the mitochondrial matrix space. Fatty acid synthase is a huge multienzyme complex composed of seven enzymes. beta-Oxidation enzymes are found infinity the cytoplasm of the cell. Beta-Oxidation enzymes are not associated with one another physically. Beta-Oxidation enzymes are bonded together to form a huge multienzyme conplex.

Explanation / Answer

Fatty acid synthase is a multienzyme complex that catalyses the formation of fatty acid palmitic acid from the substrates acetyl coA and malonyl coA. It is present in the cytoplasm and consists of seven enzymes that are associated with each other. The enzymes present in fatty acid synthase complex are ketoacyl synthase, malonyl acetyltransferase, dehydrates, enoyl reductase, ketoacyl reductase, acyl carrier protein and thioesterase.

Beta oxidation of fatty acids occurs in mitochondrial matrix. There are four enzumescinvolvedbinnbeta oxidation of fatty acids. They are acyl-coA dehydrogenase, enoyl coA hydratase, betahydroxy acyl coA dehydrogenase and thiolase. These enzymes are not physically associated with one another.

Therefore, the correct statements are the statements 2, 4, 5 and 7.
