Raug ER tau pom thoob plaws ntawm tes tab sis qhov ntom tau siab dua nyob ze ntawm lub hauv paus thiab cov cuab yeej Golgi. Ribosomes nyob rau hauv ntxhib endoplasmic reticulum raug hu ua 'membrane bound' thiab yog lub luag haujlwm rau sib sau ua ke ntawm ntau cov protein. Txoj kev no hu ua kev txhais lus.
Hais txog qhov no, yog vim li cas ntxhib ER nyob ze rau lub nucleus?
Qhov sib thooj ntawm raws ER mus rau lub cell cev muab lub ER tshwj xeeb tswj kev ua cov protein. Cov raws ER muaj peev xwm xa cov teeb liab mus rau sai cev thaum muaj teeb meem hauv kev sib xyaw protein thiab quav tshwm sim thiab yog li cuam tshuam tag nrho tus nqi ntawm kev txhais cov protein.
Tsis tas li, qhov chaw du ntawm 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.
Qhov tseeb, dab tsi yog qhov ntxhib endoplasmic reticulum muaj nuj nqi?
Rough endoplasmic reticulum yog organelle pom nyob hauv cov hlwb eukaryotic. Nws lub luag haujlwm tseem ceeb yog tsim khoom cov protein . Nws yog tsim los ntawm cisternae, tubules thiab vesicles. Lub cisternae yog ua los ntawm cov flattened membrane disks, uas tau koom nrog hauv kev hloov kho ntawm cov protein.
Puas yog qhov ntxeev endoplasmic reticulum pom hauv cov nroj tsuag lossis tsiaj txhu?
Cov ntxhib endoplasmic reticulum (RER) yog tam sim no hauv ob qho tib si cog thiab tsiaj hlwb . Nws ua lub luag haujlwm hauv kev tsim cov protein thiab ua haujlwm. Nws hu ua " ntxhib "Vim tias muaj cov membrane sib khi ribosomes ntawm nws saum npoo. RER yog tam sim no thoob plaws hauv ntawm tes tab sis qhov ntom ntom siab tshaj plaws nyob ze ntawm lub cev thiab lub cev golgi.

Dab tsi ua qhov ntxhib endoplasmic reticulum, Golgi cov cuab yeej, thiab lysosomes muaj qhov sib xws? Lawv txhua tus ua lub luag haujlwm zoo sib xws hauv lub cell. Cov protein yuav raug xa mus rau qhov kawg endoplasmic reticulum txhawm rau txheeb rau nws lub hom phiaj kawg. Cov protein tau muab tais, tom qab ntawd ntim rau thauj mus rau Golgi cov cuab yeej

Lub du endoplasmic reticulum, los yog du ER, yog ib qho organelle pom nyob rau hauv ob qho tib si tsiaj hlwb thiab cov hlwb cog. Organelle yog ib chav nyob hauv ib lub xovtooj uas muaj haujlwm tshwj xeeb. Lub luag haujlwm tseem ceeb ntawm ER du yog ua cov khoom lag luam ntawm tes zoo li cov tshuaj hormones thiab lipid

Lwm organelle hauv lub cell yog endoplasmic reticulum (ER). Thaum lub luag haujlwm ntawm cov tub ntxhais yog ua raws li lub hlwb ntawm tes, ER ua haujlwm raws li kev tsim khoom thiab ntim khoom. Nws ua haujlwm ze nrog Golgi apparatus, ribososmes, mRNA, thiab tRNA
