Qhov du endoplasmic reticulum ua haujlwm hauv ntau cov txheej txheem metabolic. Nws synthesizes lipids, phospholipids li hauv plasma membranes, thiab steroids. Cov cell uas zais cov khoom no, xws li cov qe ntshav ntawm cov qe ntshav, zes qe menyuam, thiab cov qog roj ntsha ntawm daim tawv nqaij, muaj ntau dhau ntawm cov endoplasmic reticulum.
Thaum twg qhov du endoplasmic reticulum nrhiav tau?
Discovery of Endoplasmic Reticulum (ER):
Nws tau pom nws tus kheej los ntawm Porter ( 1945) thiab Thompson (1945). Lub npe tau muab los ntawm Porter hauv xyoo 1953. Endoplasmic reticulum yog 3-dimensional, nyuaj thiab interconnected syncrri ntawm daim nyias nyias cov kab uas khiav los ntawm cytoplasm.
Koj paub li cas yog nws ntxhib lossis du endoplasmic reticulum?
Muaj ob hom ER. Ob leeg ER ntxhib thiab du ER muaj tib hom daim nyias nyias tab sis lawv muaj cov duab sib txawv. Rough ER zoo li cov nplooj ntawv lossis cov disks ntawm daim nyias nyiasthaum ER du zoo li cov hlab. Rough ER yog hu ua ntxhib vim nws muaj ribosomes txuas rau nws nto.
Yuav ua li cas thaum tus du endoplasmic reticulum malfunctions?
Kev ua haujlwm tsis zoo ntawm ER kev ntxhov siab tshwm sim los ntawm kev laus, kev hloov pauv caj ces, lossis ib puag ncig tuaj yeem ua rau ntau yam kab mob xws li mob ntshav qab zib, mob, thiab cov kab mob neurodegenerative nrog rau Alzheimer's disease, Parkinson's disease, thiab kev puas siab puas ntsws bipolar, uas yog hu ua 'conformational …
Lub hauv paus chiv keeb ntawm tus kab mob endoplasmic reticulum yog dab tsi?
Los ntawm cov txiaj ntsig ntawm txoj kev tshawb fawb no, nws pom tseeb tias muaj ob lub hauv paus chiv keeb ntawm cov txheej txheem membranous, uas yog, lub hnab ntawv nuclear thiab Golgi complex. Thaum xub thawj tus du endoplasmic reticulum tshwm nyob rau hauv ntev arrays tam sim ntawd hauv qab lub plasma membrane.
