Nyob hauv Eutherian mammals lub acrosome muaj degradative enzymes (xws li hyaluronidase thiab acrosin). Cov enzymes no rhuav tshem cov txheej txheem ntawm lub zes qe menyuam, hu ua zona pellucida, tso cai rau haploid nucleus hauv cov phev cell koom nrog haploid nucleus hauv ovum.

YYuav ua li cas enzymes nyob rau hauv acrosome?

Acrosomes ua haujlwm zoo ib yam li lysosomes thiab muaj lysosomal enzymes xws li hyaluronidase thiab acrosin.

YPuas acrosome muaj enzyme?

Lub acrosome yog ib yam tshwj xeeb ntawm cov organelle nrog lub hau-zoo li tus qauv uas npog lub anterior feem ntawm lub taub hau ntawm cov phev spermatozoon. Lub acrosome yog muab los ntawm Golgi apparatus thiab muaj digestive enzymes.

Dab tsi yog qhov ua haujlwm ntawm hydrolytic enzymes hauv acrosome ntawm cov phev?

Lub acrosome ntawm phev tsim lysins los yog hydrolytic enzymes hu ua hyaluronidase uas dissolves lub qe membrane rau fertilization ntawm ovum. Ib tus spermatozoon muaj ob lub centrioles uas tau npaj ib qho tom qab ib qho tom qab lub nucleus.

Lub luag haujlwm ntawm cov enzymes hauv fertilization yog dab tsi?

Enzymes hloov lub zog physicochemical ntawm zona pellucida kom ntxivspermatozoa raug tso tseg hauv lawv qhov kev tshawb nrhiav mus rau vitellus. Lub (depolarized) vitelline membrane nws tus kheej ua refractory rau phev txuas. Hauv vitro fertilization.
