Lack of oxygen in muscles often leads to cramps among cricketers. This results due to

A

conversion of pyruvate to ethanol

B

conversion of pyruvate to glucose

C

non - conversion of glucose to pyruvate

D

conversion of pyruvate to lactic acid

Text Solution

Verified by Experts

The correct Answer is:
D
Lactic acid produced in the muscle from the metabolism of carbohydrate in the cells . When muscles work hard (as during the time of exercise), the ament of `O_(2)` needded is used during energy production . Thus `O_(2)` lacks in the muscles.
This results to another process called anauobic metabolism. The product of this process of obtaining energy by anaerobically is lactic acid which is build up in muscles and caused pain. However , lactic acid produced helps in healing process actually.
