        During vigorous exercise, such as cycling uphill, lactic acid builds up in the muscles.

        How is this lactic acid removed during recovery?

        • excretion of lactic acid by the kidneys

        • anaerobic respiration of lactic acid in the muscles

        • aerobic respiration of lactic acid in the liver

        • excretion of lactic acid by the lungs

        Why does anaerobic respiration of glucose release less energy in muscle cells than aerobic respiration?

        1. Energy is lost in oxygen.
        2. Energy remains trapped in the chemical bonds in the molecule lactic acid.
        3. Energy remains trapped in the chemical bonds in the molecule ethanol.
        4. Energy is lost in carbon dioxide.
