Question

Quizplus · Accepted Answer

Contact of a sperm with signal molecules in the coat of an egg causes the acrosomal reaction in the sperm, which involves the release of enzymes to aid in penetrating the egg's protective layers. Mitosis, depolarization, apoptosis, and vitellogenesis are not directly related to sperm-egg interaction.
