To begin the TCA cycle, pyruvate must be converted into acetyl-Coenzyme A (acetyl-CoA) by the enzyme complex of pyruvate dehydrogenase. This complex requires 5 different coenzymes to function properly. What are they?
Is Oxaloacetate, a TCA cycle intermediate also a metabolite in gluconeogenesis? If not, which ones of these TCA cycle intermediates are also a metabolite in gluconeogenesis? Succinate Oxaloacetate Pyruvate Citrate

Fatty acid degradation stimulates the citric acid cycle through the activation of pyruvate carboxylase by acetyl-CoA. Why would the activation of pyruvate carboxylase increase energy generation from fatty acids?
Please
Below is an image of the Krebs cycle: acetyl-CoA oxaloacetate COASH H20 NADH NAD* H20 malate citrate fumarate isocitrate FADH2 NAD* CO2 FAD АТР NADH + ADP succinate GTP NAD+ a-ketoglutarate H20 GDP NADH + CO2 COASH succinyl CoA COASH Consider the conversion of succinate to fumarate, which is coupled with the production the electron carrier FADH2. If this reaction was NOT coupled with the production of FADH2 (and only catalyzed the conversion of succinate to fumarate), how would this impact ATP production through cell respiration? OATP production would stop because no high energy electron carriers would be produced ATP production would still occur, but there would be a much lower ATP yield because a large number of electron carriers are no longer being made ATP production would stop because without FADH2 we will no longer have electrons moving through the electron transport chain ATP production would still occur, but there would be a slightly lower ATP yield because a small number of…
In the complete b-oxidation of stearic acid (18:0) What is the total ATP produced in the citric acid cycle? How many moles of NADH are produced?
(b) number of moles of ATP produced under aerobic glycolysis whereby pyruvate enters the mitochondrion for oxidative decarboxylation to generate acetyl-CoA that enters the citric acid cycle. Write the reac- tions for each step using words. They need not be balanced with respect to charge, protons released or consumed, and stoichiometry. Consider 2.5 ATP/NADH oxidized and 1.5 ATP/FADH2 oxidized. Enzymes need not be named. Compare the number of moles of ATP that are produced under anaerobic glycolysis to the Of the reactions producing ATP in the mitochondrion listed in part (b) above, which are not (c) influenced by the proton gradient across the inner mitochondrial membrane?
Does Pyruvate Dehydrogenase Complex have coenzymes and Allosteric regulation?
What are the five enzymes (including regulatory enzymes) that constitute the pyruvate dehydrogenase complex? Which reactions do they catalyze?
