In reaction 1 of the Krebs cycle, acetyl-CoA formed in the pyruvate dehydrogenase reaction condenses with the four-carbon compound to form with the elimination of coenzyme A. Since the product has three carboxyl groups, this pathway is referred to as the cycle. In reaction 2 of the Krebs cycle, this product then undergoes to form The enzyme is called aconitase because the compound cis-aconitate is a(n) of the reaction. Reaction 3 eliminates CO_2 to...
