HMG-CoA is produced when and once it is made HMG-CoA can be: alanine aminotransferase breaks down alanine, which can then be converted to acetyl coA and enter the Krebs cycle O alanine aminotransferase breaks down alanine, which can then be converted to pyruvic acid for gluconeogenesis a branched chain aminotransferase breaks down valine, which can then be converted to pyruvic acid for the Krebs cycle a branched chain aminotransferase breaks down leucine, which can then be converted to acetyl coA and enter the Krebs cycle

Study Figure 19.18 and decide which of the following statements is false. Pyruvate dehydrogenase is inhibited byÂ· NIADH. Pyruvate dehydrogenase is inhibited by AÎ¤Î¡. Citrate synthase is inhibited by NADH. Succinyl-CoA activates citrate synthase. Acetyl-CoA activates pyruvate carboxylase.
Which enzyme is used for both the synthesis and breakdown of acetoacetate? thiolase O HMG-CoA synthase OB-hydroxybutyrate dehydrogenase O B-Ketoacyl-CoA transferase
What is a characteristic of an amino acid, which is ketogenic but not glucogenic? The amino acid can provide carbons for the synthesis of fatty acids The amino acid can enter the TCA cycle at the level of succinyl CoA. The amino acid can provide carbons for the net synthesis of glycogen The amino acid is NOT oxidized through the TCA cycle. The amino acid is converted to TCA cycle intermediates.
Although glucose cannot be formed from acetyl-CoA, triglycerides can enter the glycolytic pathway via which process? O Acetyl-CoA → oxaloacetate → phosphoenolpyruvate O Palmitoyl-CoAB- ketoacyl-CoA → a-ketoglutarate O Glycerol → DHAP Acyl-CoA glucose
What is the final reaction in the final round of fatty acid synthase? Acetyl-CoA ACP Transacylase Beta-Ketoacyl- ACP Synthase Beta-Ketoacyl- ACP Dehydrase Palmitoyl thioesterase Malonyl-CoA ACP Transacylase Enoyl-ACP Reductase
In the pyruvae dehydrogensae complex, acetyl-coa is released by the dihydrolipoyl transacetylase activity. What is the purpose of the following enzymatic activity.
Mammals cannot undergo net synthesis of carbohydrate from acetyl-CoA, but the carbons of acetyl-CoA can be incorporated into glucose and amino acids. Present pathways by which this could come about.
What is the common end-product of the catabolism of the branched chain amino acids that are converted to succinyl CoA? alpha-ketoglutarate glyceraldehyde phosphate oxaloacetate . propionylCoA isovalerate
A fatty acid (a long straight-chain carboxylic acid with an even number of carbons) is metabolized to acetylCoA, which can then enter the citric acid cycle to be further metabolized. A fatty acid with an odd number of carbons is metabolized to acetyl-CoA and one equivalent of propionyl-CoA. Propionyl-CoA cannot enter the citric acid cycle. Two coenzyme-requiring enzymes are needed to convert it to succinyl-CoA, a compound that can enter the citric acid cycle. Write the two enzyme-catalyzed reactions and include the names of the required coenzymes.
All of the following enzymes catalyze a committed step EXCEPT: HMG-CoA reductase Fatty acyl-CoA synthetase Acetyl-CoA carboxylase I Pyruvate dehydrogenase complex All of the above enzymes catalyze a committed step The brain can directly use all of the following chemicals as energy source EXCEPT: Acetoacetate b-hydroxybutyrate Glucose Fatty acids All of the above can directly be used by the brain as energy source
How does oxaloacetate get to the cytoplasm (from mitochondria matrix) for gluconeogenesis? oxaloacetate is converted to malate and malate is transported to cytoplasm via transporter protein. oxaloacetate gets to cytoplasm by diffusion. oxaloacetate is converted to Acetyl-CoA and Acetyl-CoA is transported to cytoplasm via transporter protein.
What is(are) the product(s) of the thiolase reaction involving a sixteen carbon ß-ketoacyl substrate and CoASH? O A 14 carbon acyl-CoA molecule and acetyl-CoA O An 18 carbon acyl-CoA molecule and acetyl-CoA O acetoacetyl coA O An 18 carbon acyl-CoA molecule
