Rating Newest Oldest. Best Answer: Alcohol and lactic acid fermentation take place in the cytoplasm, the site of glycolysis, the reaction that precedes them. The reactants are the pyruvates left over at the end of glycolysis, the products are ethanol in alcohol fermentation and lactic acid in lactic acid fermentation. These two reaction produce zero ATP--their entire function is to reset the cellular machinery so glycolysis can occur again.
Alcohol fermentation, also known as ethanol fermentation, is the anaerobic pathway carried out by yeasts in which simple sugars are converted to ethanol and carbon dioxide. Yeasts typically function under aerobic conditions, or in the presence of oxygen, but are also capable of functioning under anaerobic conditions, or in the absence of oxygen.
