what is a sperm acrosome
The acrosome reaction is the exocytosis of the acrosome, or the fusion of the acrosomal membrane with the sperm's plasma membrane. This process releases the acrosomal contents to the outside of the sperm and exposes the inner acrosomal membrane proteins on the sperm's outer plasma membrane.he function of the acrosome reaction is to help the sperm get through the egg's protective coat and to allow the plasma membranes of the sperm and egg to fuse.
