The chemical reaction of lactic acid fermentation is as follows: Pyruvate + NADH ↔ lactic acid + … Production of this acid is commonly carried out by the lactic acid bacteria, Lactobacillus spps. Fermentation is important, because it allows glycolysis to continue making ATP when oxygen is unavailable for cellular respiration. Fermentation takes place in your muscle cells during hard exercise, when not enough oxygen is available. In plant and yeast cells pyruvate is converted into carbon dioxide and a type of alcohol called ethanol. Fermentation: The process by which glucose is completely oxidized, in absence of oxygen, to form alcohol or lactic acid and a small amount of energy is said to be fermentation.
