    Each sperm contains a special organelle known as an acrosome that contains hydrolytic enzymes. It also contains numerous mitochondria. What are the likely functions of these organelles in relation to the sperms' overall functions?

    A)
    Acrosome Numerous mitochondria
    Digests through egg membranes for sperm to penetrate Provide energy for beating action of flagellum
                   

    B)
    Acrosome Numerous mitochondria
    Digests through uterine lining to reach egg Provide energy for respiration
                   

    C)
    Acrosome Numerous mitochondria
    Digests through oviducts to reach egg Direct overall activities of the sperm
                   

    D)
    Acrosome Numerous mitochondria
    Directs movement of the sperm though the female reproductive tract Provide energy for fertilization of egg

    Correct Answer: A

    Solution :

    The egg is surrounded by additional outer membranes, in addition to the cell surface membrane. The acrosomal enzymes serve to break down these membranes to bring about fusion of sperm and egg. The swimming action of the sperm by means of its flagella requires energy that is supplied by numerous mitochondria.
