Answer:
Absence of oxygen during glucose breakdown produces pyruvic acid and alcohol. ... Presence of oxygen during aerobic breakdown of glucose produces water and carbon dioxide along with the release of a large amount of energy. Hence, oxygen is necessary for the complete oxidation of glucose.
Explanation:
Scientifically, oxidation means addition of oxygen to a molecule. Various organic compounds such as carbohydrates, lipids and proteins are oxidised in presence of oxygen to release energy. The chemical bond energy which is stored in these molecules, is decomposed or oxidised in this process. Hence, complete oxidation of glucose requires oxygen.
