Cov Qauv ntawm ER zoo

Cov naj npawb ntawm zoo ER chav nyob hauv xovtooj ntawm tes nyob ntawm hom cell thiab nws xav tau kev tsim khoom li cas. Cov chav no yog nyob hauv cytoplasm, cov tshuaj zoo li gel hauv lub cell, thiab qee zaum txuas nrog ib chav ntawm ntxhib endoplasmic reticulum.

Dhau li, qhov du du endoplasmic reticulum nyob qhov twg?

Cov du endoplasmic reticulum zoo li ntxhib endoplasmic reticulum yog txuas nrog lub hnab ntawv nuclear. Cov du endoplasmic reticulum muaj cov raj zoo li tus qauv nyob ze ntawm lub xov tooj ntawm tes. Cov tubules lossis cov hlab no qee zaum ceg tsim ua lub network uas zoo li lub ntsej muag.

Ib sab saum toj no, vim li cas ER du tseem ceeb? Cov zoo ER yog tseem ceeb hauv kev sib txuas ntawm cov lipid, xws li cov roj (cholesterol) thiab phospholipids, uas ua rau txhua daim nyias nyias ntawm lub cev. Ntxiv rau nws yog tseem ceeb rau kev sib txuas thiab tso cov tshuaj steroid los ntawm cov roj cholesterol thiab lwm yam lipid ua ntej. Tsis tas li ntawd, nws koom nrog hauv cov metabolism hauv carbohydrate.

Kuj paub yog, dab tsi zoo li ER zoo li?

Ob qho ntxhib ER thiab zoo ER muaj tib yam ntawm daim nyias nyias tab sis lawv muaj cov duab sib txawv. Ntxhib ER zoo li cov ntawv los yog disks ntawm cov tawv nqaij ua pob thaum zoo ER zoo ntau dua nyiam hlab. Ntxhib ER hu ua ntxhib vim nws muaj ribosomes txuas rau nws saum npoo. ER zoo (SER) ua raws li cov khoom ntim cia.

Puas yog ER du txuas nrog lub nucleus?

Yog, Endoplasmic reticulum los yog ER yog txuas nrog rau cev , Nucleus muaj cov khoom siv caj ces (DNA) uas tsis muaj dab tsi tab sis cov ntaub ntawv khaws cia hauv daim ntawv tshuaj,. mRNA tom qab ntawd pab qhia tawm cov protein nyob hauv Ntxhib endoplasmic reticulum.
