  Glycolysis and Alcohol Fermentation When there is oxygen deficiency or prolonged exercise, muscles obtain most of their energy from an anaerobic (without oxygen) process called  glycolysis . Yeast cells obtain energy under anaerobic conditions using a very similar process called  alcoholic fermentation . Glycolysis is the anaerobic breakdown of glucose to lactic acid in lactic acid bacteria and very active skeletal muscles. This process makes energy available for cell activity in the form of ATP. Alcoholic fermentation is identical to glycolysis except for the final step.   In alcoholic fermentation, pyruvic acid is broken down into ethanol and carbon dioxide. Lactic acid from glycolysis produces a feeling of tiredness; the products of alcoholic fermentation have been used in baking and brewing. Both alcoholic fermentation and Lactic acid fermentation are anaerobic fermentation processes that begin with the sugar glucose. Glycolysis requires 11 enzymes which degrade glucose to lact
