acrosome उदाहरण वाक्य

उदाहरण वाक्य

1. A glycoprotein coat over the acrosome prevents the sperm from fertilizing the egg prior to traveling through the male and female reproductive tracts.
2. There is some evidence that this binding is what triggers the acrosome to release the enzymes that allow the sperm to fuse with the egg.
3. One should however bear in mind that a certain percentage of sperm cells will undergo a spontaneous acrosome reaction without the presence of the ovum.
4. The spermatids begin to grow a living thread, develop a thickened mid-piece where the mitochondria become localised, and form an acrosome.
5. This involves releasing the contents of the acrosome, which disperse, and the exposure of enzymes attached to the inner acrosomal membrane of the sperm.
6. Hyperactivation could then be followed by the acrosome reaction where the cap-like structure on the head of the cell releases the enzymes it contains.
7. The protein encoded by this gene is a major structural component of the ZP and functions in primary binding and stimulation of the sperm acrosome reaction.
8. The protein encoded by this gene is a structural component of the zona pellucida and functions in secondary binding and penetration of acrosome-reacted spermatozoa.
9. All of these compounds stimulate, but if they keep on stimulating, at least some of the sperm will undergo an acrosome reaction ( cap rupturing ).
10. The receptor galactosyltransferase ( GalT ) binds to the N-acetylglucosamine residues on the ZP3 and is important for binding with the sperm and activating the acrosome reaction.
