Question

produces burning sensation in our muscle during intense exercise. choose lactic acid fermentation alcoholic fermentation both oducing atp

Explanation:

During intense exercise, when oxygen supply is limited, our muscle cells undergo lactic acid fermentation. In this process, pyruvate (from glycolysis) is converted to lactic acid. The accumulation of lactic acid in the muscles leads to the burning sensation. Alcoholic fermentation occurs in yeast and some bacteria, not in human muscle cells during exercise.

Answer:

Lactic acid fermentation
