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.
When in an anaerobic environment, some cells can use glycolysis and fermentation to keep producing ATP. Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.n alcoholic fermentation, pyruvate is reduced to alcohol and releases carbon dioxide. This type of fermentation is commonly used with yeast to make alcoholic beverages and cause bread to rise. To unlock this lesson you must be a Study.com Member.
