    The process of fermentation allows the production of a small amount of ATP without oxygen. This is what allows glycolysis to continue producing ATP when oxygen is unavailable. 

    Lactic acid fermentation occurs in muscle cells

    • glycolysis splits glucose into two pyruvate molecules
    • pyruvate and NADH enter fermentation
    • energy from NADH converts pyruvate into lactic acid
    • NADH is changed back into NAD+

    Alcoholic fermentation is similar to lactic acid fermentation, this is what makes fermentation and its products important in food production (yogurt, cheese, and bread).
