Which one of the following statements about human sperm is correct?

Acrosome has a conical pointed structure used for piercing and penetrating the egg, resulting in fertilisation

The sperm lysis in the acrosome dissolve the egg envelope facilitating fertilization

Acrosome serves as a sensory structure leading the sperm towards the ovum

Acrosome serves no particular function

Solution

The sperm lysis in the acrosome dissolve the egg envelope facilitating fertilization

Penetration of human sperm is a chemical mechanism. In this, acrosome of sperm udergoes acrosomal reaction and release certain sperm lysins, which dissolves the egg envelope locally and makes the path for the penetration of sperm. Sperm lysins are acidic proteins. These sperm lysins contain a lytic enzyme hyaluronidase that dissolves the hyaluronic acid polymers in the intercellular spaces, which holds the granulosa cells of corona radiate together corona penetrating enzyme and acrosin.
