WebJun 22, 2024 · The Krebs Cycle consists of nine enzyme-catalyzed reactions that can be divided into 3 stages: 1. Acetyl CoA binds a four carbon molecule (oxaloacetate) producing a six carbon molecule (citrate). 2. Two carbons are removed as carbon dioxide. 3. The four carbon starting material is regenerated. WebIt is probable that all three reactants—citrate, cis -aconitate, and isocitrate—remain closely associated with aconitase, the enzyme that catalyzes the isomerization process, and that most of the cis -aconitate is not released from the enzyme surface but is immediately converted to isocitrate.
