Contact of a Sperm with Signal Molecules in the Coat

Question

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

Accepted Answer

The acrosomal reaction is the process by which the sperm releases hydrolytic enzymes from the acrosome that enable it to penetrate the coat surrounding the egg. This process is initiated by contact of the sperm with signal molecules on the surface of the egg. A, B, C, and D are not correct choices as they are not related to the process described.
