Answer 2

Answer: The acrosome of the sperm contains enzymes necessary for the penetration of the egg.

The acrosome is a cap present in the head of the sperm which contains all the enzymes required for penetration into the egg when fertilisation occurs. Capacitation process occurs to remove the glycoproteins found on the surface of the acrosome and this process takes place in the vagina. Without the process of capacitation the fertilisation of the egg by the sperm would not be possible.
