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.

→ 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. The net reaction is shown as:
6O2 + C6H12O6 + 38 ADP → 38ATP + 6CO2 + 6H2O
