Final answer:
The removal of the plasma membrane and glycoprotein coat located on the head of the sperm is true. During fertilization, the acrosomal reaction triggers the release of digestive enzymes that degrade the glycoprotein matrix surrounding the egg, allowing the fusion of the sperm and egg membranes.
Step-by-step explanation:
The removal of the plasma membrane and glycoprotein coat located on the head of the sperm is true. During fertilization, the sperm undergoes a series of biochemical events called the acrosomal reaction. This reaction causes the release of digestive enzymes from the acrosome, which degrade the glycoprotein matrix surrounding the egg, allowing the fusion of the sperm plasma membrane with the egg plasma membrane.
