Question

oxygen is necessary for complete oxidation of glucose.​

Answer 1

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.

Answer 2

${\huge{\boxed{\sf{\red{Answer}}}}}$

→ 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
