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.
What else can I help you with?
The acrosome of the sperm contains?
The acrosome of the sperm contains enzymes that help the sperm penetrate the egg during fertilization. It is located at the tip of the sperm's head and is essential for the process of fertilization to occur. The enzymes within the acrosome break down the outer layer of the egg, allowing the sperm to enter and fuse with the egg.
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?
The acrosome is a structure found in the head of sperm cells that contains enzymes essential for penetrating the egg during fertilization. It helps the sperm to break down the outer layer of the egg, allowing it to fuse and fertilize the egg. Thus, the acrosome plays a crucial role in the process of fertilization.
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 does the acrosome at the tip of the sperm head do?
The acrosome contains digestive enzymes that help the sperm penetrate the protective layer around the egg during fertilization. It plays a crucial role in allowing the sperm to fuse with the egg for fertilization to occur.
What is contained within acrosome?
The acrosome contains digestive enzymes that are used to break down the outer membrane of the ovum.
What is an analogy for acrosome?
A hat or a toque.

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 does the acrosome at the tip of the sperm head do?
The acrosome contains digestive enzymes that help the sperm penetrate the protective layer around the egg during fertilization. It plays a crucial role in allowing the sperm to fuse with the egg for fertilization to occur.
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.
What part of a sperm cell contains enzymes that weaken the plasma membrane of the egg?
Acrosome
What is an acroblast?
An acroblast is a material derived from the Golgi apparatus from which the acrosome develops during spermatogenesis.
