Assuming that all the 14C-labeled Acetyl-CoA formed enters the citric acid cycle at the same time, draw the citric acid cycle intermediates up to and including malate, and indicate the position of the 14C-label in each intermediate.

During acetyl CoA formation and the citric acid cycle, all of the carbon atoms that enter cellular respiration in the glucose molecule are released in the form of CO2.

Part A - Carbon atoms in acetyl CoA formation and the citric acid cycle During acetyl CoA formation and the citric acid cycle, all of the carbon atoms that enter cellular respiration in the glucose molecule are released in the form of CO2. Use this diagram to track the carbon-containing compounds that play a role in these two stages. Drag the labels from the left (which represent numbers of carbon atoms) onto the diagram to identify the number of carbon...

inThe citric acid cycle there are three reactions of the citric acid cycle it's self that are regulated: -citrate synthase which is where ATP inhibits in in citeo -isocitrate dehydrogenase: alosterrically activated by Ca2+ and ADP also is inhibited by NADH - alpha ketoglutarate dehydrogenase which is where Ca2+ increases the rate of formation of succinyl-CoA what would happen if all three of these reactions were not present? what would happen if citrate synthase was not functioning, what would happen...

What happens during the citric acid cycle?

Which reactions in the citric acid cycle are irreversible under physiological conditions, and for each of these reactions, explain why the reaction is irreversible.

True or False The citric acid cycle consumes more energy than it produces.

To enhance gluconeogenesis using acetyl CoA from the oxidation of fatty acids, the normal TCA cycle is turned off by phosphorylation of ___ and the glyoxylate cycle is turned on, instead. This cycle uses two acetyl-CoA to produce one ___ , which is also substrate for gluconeogenesis. Select one: a. isocitrate dehydrogenase ; oxaloacetate b. isocitrate lyase ; citrate c. isocitrate dehydrogenase ; citrate d. isocitrate lyase ; oxaloacetate e. None of these
