Why are muscles not killed in anaerobic respiration?

I can't imagine any reason they would be killed. What hypothesis or possible reason did you have in mind? Lactic acid? If so, lactic acid is removed from the muscles as fast as it forms. It doesn't accumulate in the muscle cells. read more

Anaerobic Respiration. Anaerobic respiration occurs during high-intensity exercises when your body works so hard there is a shortage of oxygen for energy consumption. Due to the shortage of oxygen, your body breaks down glucose and phosphates stored in your muscles for energy. The byproduct is lactic acid, which causes muscle fatigue. read more

During this short time, anaerobic respiration is used to make ATP to fuel your muscles as they run. This form of respiration is not favorable, as only 2 ATP are produced, compared to aerobic respiration, which forms 36 molecules of ATP per molecule of glucose. read more
