29. Labels. Suppose that you had an in vitro fatty acid- synthesizing system that had all of the enzymes and cofactors required for fatty acid synthesis except for acetyl CoA. To this system, you added acetyl CoA that contained radioactive hydrogen (³H, tritium) and carbon 14 (¹4C) as shown here. 3H O 14 3H-C-C-SCOA 3H The ratio of ³H/¹4C is 3. What would the 3H/14C ratio be after the synthesis of palmitic acid (C₁6) with the use of the radioactive acetyl CoA?

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
Fill in the blanks below (input numbers only!) about the metabolism of hexanoic acid, a fatty acid that is one of the components of vanilla, and whose formula is CH3(CH2)4COOH: First, the fatty acid is activated by attaching CoA, which costs ATP molecules. The fatty acid is then broken down through a beta-oxidation spiral, to make acetyl CoA molecules. This will require "turns" of the beta-oxidation process. Since each turn of the cycle yields ATP molecules, and each acetyl COA will yield ATP molecules by going through the rest of its metabolism, the net ATP molecules produced from one molecule of this fatty acid will be
