Question

represent schematically the oxidation of glucose to get energy in our
1) body cells under normal condtions
2) muscles cells during strenuous exersice

Answer 1

Explanation:

body cells under normal conditions

Answer 2

Information about oxidation of glucose is written below-

Under normal conditions, body metabolizes glucose aerobically. It produces pyruvate from glucose in cytosol.

C6H12O6 --> CH3COCOO-

C6H12O6 represents glucose.

CH3COCOO-

C6H12O6 represents pyruvate.

Under strenuous exercise, glucose is metabolized into lactic acid due to lack of oxygen. This phenomenon usually occurs in muscles.

C6H12O6 --> CH3COCOO-

--NAD+--> C3H6O3

In this reaction, NADH is reduced to NAD+.

C3H6O3 is lactic acid.

Lactic acid production causes fatigue during strenuous exercise. It is further metabolized in presence of excess oxygen when you stop exercising.
