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.

The public health nurse is presenting a health promotion class to a group of new mothers. The nurse will best define health as a state of entire physical, mental, and social well-being.
<h3>How does WHO define health?</h3>
The World Health Organization defines health as “a state of entire physical, mental, and social well-being and not merely the absence of sickness or incapacity.” Different definitions have been used over time for varied goals.
While hazardous behaviors, such as smoking or high levels of stress, can be curtailed or avoided, beneficial behaviors, such as regular exercise and getting adequate sleep, can be encouraged.
Some factors that affect health are brought on by human choices, like whether or not to adopt a risky habit, while others are the result of structural factors, such the way society is set up and how simple or challenging it is for people to get necessary healthcare services. However, other factors go beyond private.
