(C) Lactic acid fermentation is an anaerobic process that occurs in animal muscle cells during intense physical activity.When the demand for energy $(ATP)$ exceeds the supply of oxygen $(O_2)$ provided by the circulatory system,the muscle cells shift from aerobic respiration to anaerobic respiration.In this process,pyruvic acid is reduced to lactic acid by the enzyme lactate dehydrogenase,using $NADH$ as a reducing agent.Therefore,this fermentation occurs specifically due to a poor supply of $O_2$.
