Question

2. Sometimes we get painful cramps in our leg muscles after running for a long time due to the
accumulation of:
a) Hydrochloric acid
b) Fat
c) Carbon dioxide
d) Lactic acid​

Answer 1

Answer:

Lactic acid

Explanation:

During heavy exercise, the demand for energy is high but the supply of oxygen to produce energy is limited. Therefore, anaerobic respiration takes places in the muscles cells to fulfil the demand for energy. This anaerobic breakdown of glucose leads to the formation of lactic acid in muscles. The accumulation of lactic acid in muscles leads to muscle cramps.

HenceDuring heavy exercise, we get cramps in the legs due to the accumulation of Lactic acid.

So, the correct answer is 'Lactic acid'.
