Both glucose, and oxygerture reduced 1.5 pts Question 39 Why does the oxidation of organic compounds by molecular oxygen produce CO2 and water as well as release energy? a The electrons have a higher potential energy when associated with water and CO2 than they do in organic compounds. The oxidation of organic compounds can be used to make ATP Electrons are being moved from atoms that have a lower affinity for electrons (such as Carbon).to atoms with a higher affinity for electrons (such as Oxygen) The covalent bonds in organic molecules are higher energy bonds than those in water and carbon dioxide.
