The acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.
What is an acrosome?
An acrosome is a unique membranous organelle that is located over the anterior part of the sperm nucleus. It is highly conserved throughout evolution.
This acrosome contains a number of hydrolytic enzymes that help the sperm penetrate the egg's coats, when secreted.
The proteolytic enzymes such as hyaluronidase and acrosin are what help the sperm penetrate the eggs coat.
Acrosome comes from the Golgi complex of the spermatid. It consists of a protein matrix core and numerous hydrolytic and glycolytic enzymes, which are necessary for fertilization.
Therefore, the acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.

Explanation: <em>Let's pretend you're a scientist and all -</em> think about how a vaccine works. What do they contain, and why? How does our body react to a vaccine? It helps to think about a time <em>you've</em> possibly had your shots done.
Vaccines contain inactive bacteria or viruses that, when injected, tell our bodies there is an illness. This is known as the antigen. This alerts our body's immune system and as a response, our bodies release white blood cells known as antibodies to fight the illness.
