in the mitochondria pyruvate is converted into acetyl CoA so then acetyl CoA make its way to the TCA cycle and produces energy sources for oxidative phosphorylation. Pyruvate oxidation transforms pyruvate, a three-carbon molecule, into acetyl, a two-carbon molecule linked to Coenzyme A, generating NADH and releasing one carbon dioxide molecule in process the citric acid cycle is fundamental because runs on acetyl CoA as its fuel.  i need more explanantion
