Question

*While exercising due to anearobic respiration we feel tired due to the accumulation of ________ acid in the muscles of the body.*

​

Answer 1

Answer:

lactic acid

Explanation:

With pyruvate accumulation, the amount of lactic acid produced is also increased. This lactic acid accumulation in the muscle tissue reduces the pH, making it more acidic and producing the stinging feeling in muscles when exercising. This inhibits further anaerobic respiration, inducing fatigue.

Answer 2

Answer:

Lactic acid.

Due to the use of Adenosine Triphosphate (ATP) from the muscles and lactic acid accumulation of lactic acid, we feel tired.

Because the glucose is not completely broken down, and hence less energy is released than during aerobic respiration.
