In Eutherian 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.
So, correct answer is "Acrosome of sperm".
So, correct answer is "Acrosome of sperm".

Enzyme for fertilization present in Acrosome of Sperm
The process of fertilization is a crucial step in sexual reproduction. It involves the fusion of a male gamete (sperm) and a female gamete (ovum) to form a zygote. The sperm has to penetrate the protective layers of the ovum to fuse with it. For this, the sperm uses an enzyme present in its acrosome.
What is an acrosome?
The acrosome is a cap-like structure present at the tip of the sperm's head. It contains a group of enzymes called acrosomal enzymes.
What is the function of acrosomal enzymes in fertilization?
The acrosomal enzymes are responsible for breaking down the protective layers of the ovum, allowing the sperm to penetrate it. The main enzyme present in the acrosome is called acrosin. It is a protease enzyme that breaks down the proteins present in the ovum's zona pellucida.
How does acrosin work?
Acrosin is activated when the sperm reaches the ovum's surface. It creates a hole in the zona pellucida, allowing the sperm to penetrate and fuse with the ovum's membrane.
Conclusion:
In conclusion, the enzyme necessary for fertilization is acrosin, which is present in the acrosome of the sperm. The acrosomal enzymes present in the acrosome are essential for breaking down the protective layers of the ovum, allowing the sperm to penetrate it and fuse with it.
