The acrosomeis a unique membranous organelle located over the anterior part of the sperm nucleus that is highly conserved throughout evolution.
The acrosome contains proteolytic enzymes such as hyaluronidase and acrosin, which help sperm in penetrating the zona pellucida layer of the ovum and enter the cytoplasm of the ovum so that the nucleus of sperm and the ovum can fuse together.
Enzyme produced by acrosome: Acrosome contains many enzymes such as hyaluronidase, acrosin, acid phosphatase, etc.
