B fertilizin

Explanation:

Fertilizin-antifertilizin Reaction. The Jelly covering of the egg had hypothetical receptor molecules which he termed fertilizin.

Answer 2

The jelly covering of the egg has receptor molecules, that are called as

b. Fertilizin

• The outer jelly like covering of the ovum contains of many receptor molecules called Fertilizin. These receptors attract the sperms to the particular sites.
• The Fertilizin contains carbohydrates and amino acids which help in attracting their counterparts: the antifertilizin.
• The sperms have receptor molecules called antifertilizin which go and bind to the fertilizin at the the time of fertilisation by lock-key mechanism.
• The sperm which reaches the ovum first and binds with the Fertilizin receptor fuses and a successful fertilisation occurs.
