The product detaches from the fatty acid synthase complex when the chain length is usually 18 carbons. Oxaloacetate carries acetyl CoA to the cytosol.
Which of the following statements is TRUE about fatty acid biosynthesis? Citrate carries malonyl CoA to the cytosol. O Acetyl ACP is the donor of the acetyl group. O NADPH is used as the reducing equivalent in the process. O The product detaches from the fatty acid synthase complex when the chain length is usually 18 carbons.
What is incorrect in the diagram shown below? Mall-com Thiolysis SCOA + H₂S-Co COA Acetyl CoA Acetyl CoA H₂C The products should be acetyl CoA and propionyl CoA. Sulfur should not be present in any molecular structure. Acyl group cleavage occurs in a different step of the B-oxidation pathway. The B-oxidation pathway directly generates ATP, which is not shown here.
