Question

Function of protein binding in acrosomal process is to

• A. Prevent polyspermy
• B. Digest vitelline layer
• C. Ensure fertilization of egg by a sperm of same species
• D. Severe the sperm tail

Answer 1

The correct option is C Ensure fertilization of egg by a sperm of same species

The binding of the sperm to the zona pellucida layer is induced by the ZP3 proteins during the acrosomal reaction. This protein binding is species specific, so as to ensure that the egg is fertilized by the sperm of the same species.

So, the correct option is 'Ensure fertilization of the egg by a sperm of same species'.
