Lack of oxygen in muscles often leads to cramps among cricketers. This results due to the ___________.
Lack of oxygen in muscles often leads to cramps among cricketers. This results due to the ___________.
The correct option is D Conversion of pyruvate to lactic acid
The correct answer is option D.
Explanation of correct option:
- The anaerobic breakdown of pyruvic acid which takes place in the mitochondria leads to the formation of lactic acid.
- When a person performs strenuous exercises and workouts the oxygen gets used up.
- This leads to a lack of oxygen in the muscles and the lactic acid forms and gets accumulated in the muscles leading to muscle cramps.
Explanation for incorrect options:
Option A:
Under anaerobic conditions, pyruvate can be converted to ethanol in which acetaldehyde is an intermediate product and it releases CO2 thus forming ethanol.
Option B:
The process by which pyruvate is converted to glucose is called gluconeogenesis.
Option C:
Non-conversion of glucose to pyruvate leads to interruption of glycolysis in which glucose is converted to pyruvate.
Final answer: Lack of oxygen in muscles often leads to cramps among cricketers. This results due to the conversion of pyruvate to lactic acid.
