What chemical builds up in muscle tissue when an anaerobic process is used to produce energy for muscle contraction?

Question

Quizplus · Accepted Answer

During anaerobic respiration in muscles, when oxygen levels are insufficient for aerobic respiration, lactic acid is produced as a byproduct. This process allows for the continued production of energy (ATP) when oxygen is scarce, but leads to the accumulation of lactic acid in the muscle tissue, which can cause muscle fatigue and soreness.
