Depolarization of the oocyte plasma membrane occurs when the first sperm attaches to the integrin $\alpha$ 6$\beta$1.This is called the
A)slow block to polyspermy.
B)acrosomal reaction.
C)fast block to polyspermy.
D)fertilization.
E)spermiogenesis.

Question

Quizplus · Accepted Answer

Depolarization of the oocyte plasma membrane is part of the fast block to polyspermy, which occurs when the first sperm attaches to the integrin F1F1F1S1F1F1F106F1F1F1S1F1F1F101. The fast block to polyspermy involves rapid changes in the oocyte membrane potential and physical changes to the zona pellucida, making it impenetrable to other sperm. Therefore, the best choice is C, fast block to polyspermy.
