Lactic Acid Fermentation


        Lactic acid fermentation occurs in our
        muscles during heavy exercise, when
        oxygen levels have been depleted in our
        muscle cells.


        Without oxygen, the cells use
        fermentation to obtain energy. Lactic acid
        is also produced and causes muscles to
        feel weak and sore.
