Question

1. Lack of oxygen in muscles often leads to cramps among cricketers. This results due to
a) conversion of pyruvate to lactic acid
b) conversion of pyruvate to glucose
c) non conversion of glucose to pyruvate
d) conversion of pyruvate to ethanol​

Answer 1

Answer:

options a

Explanation:

conversation of pyruvate to lactic acid

Answer 2

Answer:

option (D) is the correct answer

Explanation:

Intracellular acidosis occurs due to lactic acid accumulation, it has been regarded as the most important cause of skeletal muscle fatigue. Lactic acid is formed and accumulated in the muscle under conditions of high energy demand, rapid fluctuations of the energy requirement and insufficient supply of oxygen. Subsequently, the pyruvate synthesised during glycolysis is converted to lactic acid in anaerobic condition. Thus, the correct answer is option D.
