From the statements below, which of the following is inaccurateconcerning fatty acid metabolism? Both processes use mobile electron carriers Both beta oxidation and fatty acid synthase use a carrier group The first step in fatty acid degradation pathway and biosynthetic pathway are regulated C2 unit of acetyl moiety is used in both fatty acid degradation and fatty acid biosynthesis Both processes occur in a unique, specific location (Compartmentalization)
Which of the following is NOT part of the multi-enzyme complex of fatty acid synthase? O enoyl-ACP reductase O acetyl CoA carboxylase O 3-hydroxybutyrylACP-dehydratese O B-ketoacyl-ACP reductase
Which of the following statements is TRUE about fatty acid biosynthesis? Group of answer choices: NADH is used as the reducing equivalent in the process. Malonyl ACP is the donor of the acetyl group. The product detaches from the fatty acid synthase complex when the chain length is usually 18 carbons. Oxaloacetate carries acetyl CoA to the cytosol.

Decide whether each of the following statements is true about leucine transaminase. It's an enzyme, and leucine is its substrate. It speeds up the rate at which leucine is converted to other substances. It's a small molecule, with a molecular weight around 50 mol If you were to write a chemical equation for certain biochemical reactions of leucine, leucine transaminase would appear on both sides.

Years ago there was interest in using uncouplers such as dinitrophenol as weight control agents. Presumably, fat could be oxidized without concomi- tant ATP synthesis for re-formation of fat or carbohydrate. Why was this a bad (i.e., fatal) idea?

Catabolism of triacylglycerols- beta-oxidation pathway Biosynthesis of fatty acids from Acetyl CoA Glycolysis (from glucose to two molecules of pyruvate) Conversion of Pyruvate to Acetyl CoA Citric acid cycle Gluconeogenesis pathway (pyruvate to glucose)
All of the following are accurate contrasts for beta oxidation vs fatty acid synthesis except which of the following statements? Group of answer choices The hydroxylacyl group differs in stereochemistry between beta oxidation and biosynthesis CoA is the acyl carrier group in beta oxidation, acyl carrier protein is the carrier in biosynthesis The carbon unit resulting from beta oxidation is acetyl-CoA, the carbon unit for biosynthesis is malonyl-CoA FAD is an electron acceptor in beta oxidation, NADP+ is the electron acceptor in biosynthesis
