Question

Quizplus · Accepted Answer

Cortical reaction is responsible for preventing polyspermy. When the sperm penetrates the egg's plasma membrane, it stimulates the cortical reaction that releases cortical granules. The cortical granules release enzymes that create a fertilization membrane. This membrane prevents additional sperm from entering the egg, thus preventing polyspermy.
