We know that single bonds are weaker than the double bonds. It can says that the double bonds are stronger than the single bonds.The single bond is formed between two electrons and double bonds are formed between four electrons.
When double bonds are formed between two atoms then one is sigma bond and other is pi bond .Sigma bonds are formed by hybridization between s- s orbital and pi bonds are formed between un-hybridized p- orbitals.
Therefore, Double bonds are stronger than the single bond.Hence, C=O is strongest bond.
<span>You need to have NAD+ as a source of oxidation for the pyruvate, as well as a supply of coenzyme A. CO2 is released by the pyruvate as a carboxyl group is removed</span>
