- Study Figure 19.18 and decide which of the following statements is false. Pyruvate dehydrogenase is inhibited by· NIADH. Pyruvate dehydrogenase is inhibited by AΤΡ. Citrate synthase is inhibited by NADH. Succinyl-CoA activates citrate synthase. Acetyl-CoA activates pyruvate carboxylase.arrow_forwardIf the conversion of glycerol to glyceraldehyde 3-phosphate releases 1 molecule of ATP, how many molecules of ATP are released during the conversion of glycerol to pyruvate?arrow_forwardThe conversion of 1 mol of fructose 1,6-bisphosphate to 2 mol of pyruvate by the glycolytic pathway results in what type of net formation?arrow_forward
- Two carbon atoms are fed into the citric acid cycle as acetyl-CoA. In what form are two carbon atoms removed from the cycle?arrow_forwardThe conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate is the only oxidative reaction of glycolysis. True or false?arrow_forwardfatty acid breakdown generates a large amount of acetyl CoA. What will be the effect of fatty acid breakdown on pyruvate dehydrogenase complex activity? On glycolysis?arrow_forward
- What three steps are included in the breakdown of pyruvate? Explain the importance of AcetylCo A as a regulatory molecule for cellular respiration.arrow_forwardIf glutamate were labeled with C-14 at the delta-carbon and added via transamination to the citric acid cycle to produce alpha-ketoglutarate, how long would it take for the compounds containing C-14 to be reduced by 25% (assume 10 seconds per turn of the cycle)?arrow_forwardWhat is the key enzyme of glycolysis which catalyzes the production of fructose-1,6-bisphosphate?arrow_forward
- How similar of an effect would a mutation in pyruvate dehydrogenase have, compared to a mutation in pyruvate carboxylase that blocks its ability to be regulated by acetyl-CoA?arrow_forwardWhich citric acid cycle intermediates can be directly used in gluconeogenesis? Which can be used for fatty acid synthesis? Which can be directly converted to amino acids?arrow_forwardHow many acetyl CoA molecules can be produced during the complete β-oxidation of this fatty acid?arrow_forward
