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. The process of alcohol fermentation allows yeasts to break down sugar in the absence of oxygen and results in byproducts that humans benefit from.his part is known as glycolysis. In the second part, the 2 pyruvate molecules are converted into 2 carbon dioxide molecules and 2 molecules of ethanol, otherwise known as alcohol. This second part is called fermentation.
