Vedclass · Answer

(D) Sperm lysins are a group of hydrolytic enzymes present in the acrosome of the sperm. These enzymes facilitate the penetration of the sperm through the layers of the ovum during fertilization. The acrosome contains enzymes such as hyaluronidase (which digests hyaluronic acid in the corona radiata),corona penetrating enzyme,and acrosin (a protease that helps in penetrating the zona pellucida). Therefore,all the listed enzymes are components of sperm lysins.
