Detailed explanation-1: -It contains proteolytic enzymes such as hyaluronidase and acrosin that help the sperm in penetrating the ovum through the zona pellucida layer around the ovum and enter the cytoplasm of the ovum.

Detailed explanation-2: -In placental mammals the acrosome contains degradative enzymes (including hyaluronidase and acrosin). These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.

Detailed explanation-3: -Normal sperm cells have an oval-shaped head with a cap-like covering called the acrosome. The acrosome contains enzymes that break down the outer membrane of an egg cell, allowing the sperm to fertilize the egg.
