in muscle cells, fermentation produces
Lactic Acid Fermentation. Glycolysis is a metabolic reaction in which glucose is broken down to produce a substance called pyruvate. Pyruvate is the end product of the process of glycolysis, and it supplies energy to the muscles.Pyruvate provides energy to cells when oxygen is present by oxidizing to produce carbon dioxide. In anaerobic conditions, the pyruvate ferments to produce lactic acid.The lactic acid is used by your muscle cells to continue the process of metabolism of glucose for energy production.actic Acid Fermentation.
