The acrosome reaction must be completed before the sperm can fuse with the secondary oocyte, during the process of fertilisation. It occurs when the sperm comes into contact with the corona radiata of the secondary oocyte. Initally, perforations will develop in the acrosome, and then there will be point fusions of the sperm plasma membrane and the outer acrosomal membrane.
The acrosome reaction is associated with the release of enzymes which facilitate fertilisation. The passage of sperm through the corona radiata is dependent on hyaluronidase, an acrosomal membrane, as well as tubal mucosal enzymes. Flagella action of the sperm also helps penetration of the corona radiata. Other important acrosomal enzymes include esterases, and lysin which causes lysis of the zona pellucida.

The acrosome of the sperm contains?
In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).
Acrosome of sperm is derived from which cell organelle?
The acrosome is derived from the Golgi apparatus and contains hydrolytic enzymes.it comes from the testes
What is the importance of acrosome?
it carries enzymes that help the sperm to penetrate the egg.
The acrosome of a sperm cell contains?
fdfd
What chemicals come out of the acrosome that help the sperm get into the egg?
The acrosome layer of sperm cells contain enzymes to break down the outer layer of the ovum to allow penetration by the sperm cell.
The acrosome of the sperm contains?
In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).
What is contained within acrosome?
The acrosome contains digestive enzymes that are used to break down the outer membrane of the ovum.
Acrosome of sperm is derived from which cell organelle?
The acrosome is derived from the Golgi apparatus and contains hydrolytic enzymes.it comes from the testes
What is the importance of acrosome?
it carries enzymes that help the sperm to penetrate the egg.
What is an analogy for acrosome?
A hat or a toque.
What does the sperm cell use to penetrate the egg?
The sperm structure containing enzymes to break down the egg's protective coating is called the Acrosome.
The acrosome of a sperm cell contains?
fdfd
The anterior end of the sperm is called?
acrosome
What chemicals come out of the acrosome that help the sperm get into the egg?
The acrosome layer of sperm cells contain enzymes to break down the outer layer of the ovum to allow penetration by the sperm cell.
What do sperm cells have in their heads?
There is a specialized lysosome. It is called acrosome
What is the function of acrosome?
The acrosome is a structure that develops over the back half of a sperm. It contains proteins that are released when the sperm makes it to the egg & helps the sperm penetrate the egg. there is a good definition available in Wikipedia, for this, no need to rehash it here.
What part of a sperm cell contains enzymes that weaken the plasma membrane of the egg?
Acrosome
