The Cortical Reaction Functions Directly in The

Question

The cortical reaction functions directly in the
A)formation of a fertilization envelope.
B)production of a fast block to polyspermy.
C)release of hydrolytic enzymes from the sperm cell.
D)generation of a nerve-like impulse by the egg cell.
E)fusion of egg and sperm nuclei.

Accepted Answer

The cortical reaction is a process that occurs immediately after the sperm cell fuses with the egg cell, leading to the release of enzymes that form a fertilization envelope. This envelope serves as a barrier to prevent additional sperm from fertilizing the egg, thus providing a fast block to polyspermy.
