which of the following is produced abundantly following glycolysis during anaerobic respiration causing cellular and blood ph to lower, contributing to muscle fatigue?
glycolysis
pyruvic acid
creatine phosphate
lactic acid

Explanation:

During anaerobic respiration, after glycolysis, pyruvic acid is converted to lactic acid. Lactic acid accumulation lowers pH (as it is acidic) and contributes to muscle fatigue. Glycolysis is the process itself, not the product causing the pH - lowering. Creatine phosphate is involved in energy transfer (e.g., regenerating ATP) but not in this pH - lowering, muscle - fatigue - causing scenario.

Answer:

Lactic Acid
