Step 1
The reaction catalysed by acetyl-CoA carboxylase is the formation of malonyl-CoA from acetyl-CoA. This is the first step in fatty acid synthesis and is considered the committed step because it is highly regulated and irreversible. Show more…

Select the phrase that best completes this sentence. Acetyl-CoA in a liver cell can be used to make pyruvate, fatty acids, and ketone bodies. in the citric acid cycle and to create fatty acids and ketone bodies. in the citric acid cycle and to make pyruvate. to make ketone bodies, but not fatty acids or pyruvate.

Which statement about fatty acid synthesis is correct? Fatty acids cannot be synthesized from acetyl-CoA units derived from glucose. Although malonyl-CoA molecules are three carbons in length, only carbons-1 and -2 of malonyl-CoA are incorporated into fatty acids. Fatty acid synthesis reactions proceed via a repeating cycle of condensation-reduction-hydration-oxidation steps. The chain elongation reactions of fatty acid synthesis occur in the mitochondrial matrix.

Which of the following answers completes the sentence correctly? Regulation of fatty acid biosynthesis occurs at the enzymatic step catalyzed by: carnitine acyltransferase acetyl CoA carboxylase pyruvate carboxylase citrate synthase citrate-malate translocase
