Muscle Fatigue Can Be Caused By

Question

Muscle fatigue can be caused by
A)increased ADP.
B)insufficient oxygen.
C)depletion of creatine phosphate.
D)increased lactic acid.
E)all of the choices are correct.

Accepted Answer

All of the choices can cause muscle fatigue to some extent. Increased ADP indicates that cellular respiration is producing more waste products and may not be keeping up with energy demand. Insufficient oxygen can lead to anaerobic respiration and the buildup of lactic acid. Depletion of creatine phosphate means that the muscle no longer has a readily available source of energy. Increased lactic acid can lower pH levels, leading to muscle fatigue.
