ESSAY
38. ANS:
Both main types of fermentation release energy from food molecules by producing ATP in the
absence of oxygen. Alcoholic fermentation occurs in yeasts and a few other microorganisms, and
its products are alcohol, CO2, and NAD+. Lactic acid fermentation occurs in muscle cells and
some unicellular organisms, and its products are lactic acid and NAD+.
