Question

oxygen is necessary for complete oxidation of glucose ?

Answer 1

In glycolysis, a 2 ATP investment results in a 4 ATP payoff. Unlike the rest of aerobic respiration, which takes place in the mitochondria, glycolysis takes place in the cytoplasm of the cell. Unlike the rest of aerobic respiration, glycolysis does not require oxygen.

Answer 2

Here's the answer

When glucose is completely oxidised in aerobic respiration, it produces 38 molecules of ATP.

In cellular respiration, three processes take place one after the other. They are Glycolysis , Krebs cycle and election transfer chain reaction.

In absence of oxygen , Glycolysis can occur only but other further reaction will not take place.

If Glycolysis occurs in the absence of oxygen, it produces alcohol. By anaerobic Glycolysis, only 2 molecules of ATP are produced. This results in less energy supply to the body.

Therefore, Oxygen is necessary for complete oxidation of glucose.
