Contact of a sperm with signal molecules in the jelly layer of an egg causes the sperm to undergo ________.
A) mitosis
B) depolarization
C) apoptosis
D) vitellogenesis
E) the acrosome reaction

Question

Quizplus · Accepted Answer

The interaction of sperm with the jelly layer surrounding the egg triggers the acrosome reaction, which is essential for fertilization of the egg. The acrosome reaction involves the release of digestive enzymes from the acrosome of the sperm, which enables it to penetrate the jelly layer and ultimately the egg. Depolarization, mitosis, apoptosis, and vitellogenesis are not associated with the initial interaction of sperm with the egg.
