APAKAH MAKSUD ACROSOME REACTION dalam CORSICA?
Tindak balas acrosome
Semasa persenyawaan, sperma mesti sekerap pertama dengan membran plasma dan kemudian menembus telur betina untuk menyuburkannya. Fusing ke telur biasanya menyebabkan masalah kecil, sedangkan penembusan melalui telur keras telur dapat memberikan lebih banyak masalah kepada sperma. Oleh itu, sel-sel sperma melalui proses yang dikenali sebagai tindak balas acrosome yang merupakan tindak balas yang berlaku dalam acrosome sperma kerana ia menghampiri telur. Acrosome adalah struktur seperti topi di bahagian belakang anterior kepala sperma. Apabila sperma menghampiri zona pellucida telur, yang diperlukan untuk memulakan tindak balas acrosome, membran mengelilingi sekumpulan acrosome dengan membran plasma oosit, mendedahkan kandungan acrosome. Kandungannya termasuk antigen permukaan dan banyak enzim yang bertanggungjawab untuk memecahkan lapisan telur yang telus dan membolehkan persenyawaan berlaku.
Definisi acrosome reaction dalam kamus Corsica
Takrif tindak balas acrosome dalam kamus adalah pembebasan enzim dari acrosome apabila sperma bertemu dengan ovum, yang membolehkan gabungan dengan ovum dalam proses pembiakan seksual.

Although the dramatic assembly of actin in marine invertebrate sperm
undergoing the acrosome reaction is serving as a model for the exploration of the
actin behavior, questions remain about the acrosome reaction in mammalian
