    Lactic Acid Fermentation
    • The fermentation method used by animals and certain bacteria, like those in yoghurt, is lactic acid fermentation.
    • This type of fermentation is used routinely in mammalian red blood cells and in skeletal muscle that has an insufficient oxygen supply.
    • In muscles, lactic acid accumulation must be removed by the blood circulation and the lactate brought to the liver for further metabolism. 
    • The lactic acid fermentation can be depicted as:
    • Pyruvic acid+NADH↔Lactic acid+NAD+
    • The enzyme responsible for this reaction is lactate dehydrogenase (LDH).
    • In order to regenerate more NAD, the pyruvic acid is broken down into lactic acid.\
