As a sperm cell finally approaches its final target, its acrosome becomes activated.  The acrosome is a specialized organelle found in the cell’s head region and activation results in the exocytosis of several types of proteolytic enzymes. Name 2 specific proteins you might expect the enzymes released by the acrosome to breakdown. What purpose does this play in the fertilization of the egg? Explain your reasoning.
