- True or false The conversion of pyruvate to acetyl coa requires energy input into the format of atpAfter several days of starvation, the capacity of the liver to metabolize acetyl-CoA via the citric acid cycle is greatly diminished. Explain.Indicate whether each of the following statements is true or false. If false, correct the statement or provide a brief explanation for why it is false. Malonyl-CoA inhibits carnitine acyltransferase II , thus slowing transport of fatty acyl-CoA into mitochondrial matrix.
- The acetyl group of acetyl-CoA is derived from the breakdown of lipids, carbohydrates, and certain _____________.Although both acetyl-CoA and succinyl-CoA are high-energy thioesters, their chemical energy is used in distinct ways. Elaborate.TRUE or FALSE: Fatty acids are synthesized thru a chain of elongation that starts from Acetyl-CoA as the precursor molecule.
- The same reactions that were seen in the process of converting pyruvate to acetyl-S-CoA, occur in step ____ of the citric acid cycle as ____________ is converted to _________________.fatty acid store potential energy that can be used to create ATP in the Krebs citric acid cycle true or falseBefore a fatty acid can undergo β-oxidation, it must be activated and then shuttled across the inner mitochondrial membrane. The activating agent and shuttle molecule are, respectively: A. CoA and carnitine B. CoA and citrate C. acetyl CoA and carnitine D. acetyl CoA and citrate
- Which of the following intermediates serve as the brain’s primary source of energy during prolonged starvation? Group of answer choices acetyl CoA pyruvate fatty acyl CoA glucose acetoacetateAfter several days of starvation, the ability of the liver to metabolize acetyl-CoA via the citric acid cycle is severely compromised. Explain why. Your explanation should NOT exceed 20 words. The 21st word onwards will not be read and considered.Acetyl-CoA is produced when ____ is broken down.
