Question

Sperm's acrosome has

• A. Acid phosphatase, hyaluronic acid and proacrosin
• B. Hyaluronic acid, acid phosphatase and Fertilizin
• C. Hyaluronidase, proacrosin, and acid phosphatase
• D. Fertilizin, proacrosin and acid phosphatase

Answer 1

Answer: (C)

The acrosome of sperm contains lytic enzymes such as cathepsin, acid phosphatase, hyaluronidase, proacrosin. Hyaluronidase enzyme is found particularly in the sperms of mammals. This enzyme dissolves corona radiata enables the sperm to penetrate through it. Proacrosin changes into acrosin and helps to dissolve the zona pellucida layer of the ovum.
