When one mole of pyruvate is metabolized through the pyruvate dehydrogenase complex and the citric acid cycle, it produces 12.5 moles of ATP in normally respiring mitochondria. Identify the steps where energy is conserved and account for the generation of 12.5 moles of ATP in this metabolic pathway. For each of the steps you need to provide the complete enzyme name and the energy or activated carrier produced at that step. Finally, you should show how your energy & activated carriers account for the total 12.5 moles of ATP produced
