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.
Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process. It also takes place in some species of fish where it provides energy when oxygen is scarce. Ethanol fermentation has many uses, including the production of al
