What is the primary function of the acrosome in the fertilization process?

To allow the sperm to attach to the egg

To release enzymes that break down the egg's coating (correct)

To contain the genetic material of the sperm

To provide energy for the sperm to swim

What is the main effect of the cortical granule reaction during oocyte activation?
