Question

Why oxygen is necessary for complete oxidation of glucose

Answer 1

In respiration, the energy from the oxidation of glucose and the reduction ofoxygen is captured in ATP. Organic molecules that have plenty of hydrogen are rich in energetic electrons that release their potential energy when they fall closer to theoxygen.

Answer 2

Aerobic respiration. The glucose andoxygen react together in the cells to produce carbon dioxide and water. The reaction is called aerobic respiration because oxygen from the air is neededfor it to work.
