Question

Oxygen is necessary for complete oxidation of glucose ...why?

Answer 1

heya !!!

■Oxidation is the process of gain of oxygen to a compound due to which it's chemical composition changes or loss of hydrogen atoms .

■This process can be aerobic or anaerobic .

■AEROBIC oxidation is the process by which the metabolism of sugars and fatty acids takes place in the presence of oxygen to produce energy giving ATP .

■Glucose is oxidized in presence of Oxygen.

■oxygen is necessary for the complete oxidation of glucose because it is an aerobic reaction .

■oxygen act as oxidizing agent .

hope it helps u dear ^_^

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.

Thanks!
