Question

Oxygen is necessary for complete oxidation of glucose​

Answer 1

Answer:

Yes.

Explanation:

The oxidisation of glucose can be in three possibilities

1) Presence of Oxygen (Aerobic)

2) Absence of Oxygen (Anerobic)

3) Lack of Oxygen (Anerobic)

1) Presence of Oxygen

In presence of oxygen glucose is coverted into pyruvate in cytoplasm and then it is breakdown in mitochondria to form Energy, water and carbon dioxide.

2) Absence of Oxygen

In absence of oxygen it is breakdown in mitochondria to form ethanol and energy

3) Lack of Oxygen

In lack of oxygen pyruvate is converted into lactic acid in muscle.

(Humans perform aerobic respiration for complete breakdown of glucose to satisfy there high energy needs.)

In anaerobic respiration partial breakdown of glucose which does not gives much energy.

Answer 2

Answer:

1. Aerobic cellular respiration is the process by which cells use oxygen to help them convert glucose into energy.
2. WITHOUT OXYGEN GLUCOSE WILL BE IN COMPLETELY OXIDIZED AND VERY LESS ENERGY IS PRODUCED.
3. IN THIS PRESENCE OF OXYGEN GLUCOSE IS COMPLETELY OXIDIZED TO PRODUCE MORE ENERGY.
4. THEREFORE OXYGEN IS NECESSARY FOR COMPLETE OXIDATION OF GLUCOSE.
