WebFumaric acid is hydrated, thanks to fumarase, to malic acid and the latter is oxidized by the effect of malate dehydrogenase, a NAD + enzyme, to oxaloacetic acid, thus closing the cycle. The oxaloacetic acid formed can again bind a new acetyl group which, in its turn, will be oxidized to CO 2 + H 2 O after one turn of the cycle and so on.. The CO 2 formed in … WebAnd finally, a third way that this cycle is regulated is by looking substrate availability. And this is exactly what it sounds like. Essentially, if the body doesn't have a lot of acetyl-CoA around for example, remember this is one of the major kind of substrates for this pathway.

WebThe Krebs cycle starts with pyruvic acid from glycolysis. Each small circle in the diagram represents one carbon atom. For example, citric acid is a six carbon molecule, and OAA (oxaloacetate) is a four carbon molecule. Follow what happens to the carbon atoms as the cycle proceeds. WebThe citric acid cycle is controlled through the enzymes that catalyze the reactions that make the first two molecules of NADH. These enzymes are isocitrate dehydrogenase and α-ketoglutarate dehydrogenase. When adequate ATP and NADH levels are available, the rates of these reactions decrease.
