WebApr 9, 2024 · The 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. WebDec 24, 2024 · Steps in the Citric Acid Cycle. Step 1. The first step is a condensation step, combining the two-carbon acetyl group (from acetyl CoA) with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate. CoA is bound to a sulfhydryl group (-SH) and diffuses away to eventually combine with another acetyl group.
WebStep 1. In the first step of the citric acid cycle, acetyl \text {CoA} CoA joins with a four-carbon molecule, oxaloacetate, releasing the \text {CoA} CoA group and forming a six-carbon molecule called citrate.
