Each of the following enzymes are similar in that they are all regulation points for the pathway/cycle they operate in ... except for one enzyme. Which of the following is not a regulated enzyme? CPyruvate carboxylase Transketolase C Glycogen phosphorylase C Citrate Synthase Phosphofructokinase Acetyl CoA carboxylase

What enzyme will not be used if the oxidative portion of the pentose phosphate pathway is operating to produce ribose 5-phosphate? Ribulose 5-phosphate isomerase 6-phosphoglucono-lactonase 6-phosphogluconate dehydrogenase Transaldolase

Arsenate can replace inorganic phosphate in the reaction catalyzed by glyceraldehyde-3-phosphate dehydrogenase, causing glyceraldehyde-3-phosphate to be directly converted to 3-phosphoglycerate(NADH is still formed). Which of the following is absolutely true in case of arsenate poisoning -Glycolysis will stop - Glycolysis will still proceed with no net ATP gain - Glycolysis will not generate any form of energy  - Glycolysis will still proceed, but with a net consumption of ATP - Glycolysis will proceed with lactate as end product

When acetyl-CoA containing radioactively labeled carbon atoms is fed to cells, the CO, produced is not initially radioactive. However, molecules of citrate and oxaloacetate are radioactive. Only after some time has passed will radioactive CO2 be released. What is the best explanation for this observation?

Which of the following catalyzes a step that does NOT produce CO2? Group of answer choices alpha-ketoglutarate dehydrogenase complex malate dehydrogenase pyruvate dehydrogenase complex isocitrate dehydrogenase   Citrate synthase is regulated by... Group of answer choices Concentrations of substrate and products Fructose-2,6-Bisphosphate Covalent modification Allosteric regulation by the levels of NADDH

alpha-ketoglutarate dehydrogenase will do which of the following: Select one: a. Pyruvate is decarboxylated to become acetyl-CoA producing NADH and Carbon dioxide b. Succinate is oxidized to become fumarate forming FADH2 c. Succinyl-CoA becomes Succinate and forms one ATP molecule and Coenzyme A-SH d. Oxaloacetate combines with the acetyl from acetyl-CoA to produce Citric acid(citrate) e. Malate is oxidized to become oxaloacetate forming NADH f. Isocitrate and then decarboxylated and oxidized to produce alpha-ketoglutarate, Carbon dioxide and NADH g. Citrate is rearranged to become Isocitrate h. Fumarate is combined with water to become Malate i. alpha-ketoglutarate is oxidized and decarboxylated to produce Succinyl-CoA, Carbon dioxide and NADH

Once formed, what are the three possible fates of pyruvate and under what conditions do they occur? Match the appropriate pairs.   Clear All pyruvate forms lactate pyruvate forms ethanol pyruvate forms acetyl-CoA   under anaerobic conditions in animals under aerobic conditions under anaerobic conditions in yeast and other microorganisms

If you added an inhibitor of succinyl CoA synthetase to a cell actively undergoing the citric acid cycle, which of the following would be a direct and immediate result? O glucose would be produced O high energy triphosphate would not be formed via substrate level phosphorylation the delta G of the reaction would be reduced O CoA would not be added to fumarate   Please don't provide handwriting solution
