Certain microorganisms with an incomplete citric acid cycle decarboxylate a-ketoglutarate to produce succinate semialdehyde. A dehydrogenase then converts succinate semialdehyde to succinate. Соо Coo CH, CH, NAD NADH CH, CH CH Co COO 000 -ketoglutarate Succinate Succinate semialdehyde These reactions can be combined with other standard citric acid cycle reactions to create a pathway from citrate to oxaloacetate that bypasses the reaction catalyzed by Dehydrogenase Tha reaction, a step that is accompanied by the...

Assume a cell has just completed glycolysis and the resulting
pyruvate has a c-14 radio label on carbon -1. Highlight the carbon
on the attached pages as it passes through the PDH complex and the
TCA cycle until it is lost as CO2. If only a portion of the carbons
are lost stop highlighting when the CO2 first starts to come off.

1. Select the TRUE statement about the citric acid cycle. A. Isocitrate dehydrogenase is a multienzyme complex that is very similar to the pyruvate dehydrogenase complex B. The two decarboxylation steps occur right after each other, first via oxidative alpha- decarboxylation, then via oxidative beta- decarboxylation. C. In one turn of the cycle, the two carbons that enter the cycle as acetyl CoA are the same two carbons that are released as CO2. D. A flavin containing dehydrogenase enzymes oxidizes...
