Rough endoplasmic reticulum yog ib qho organelle pom nyob rau hauv eukaryotic hlwb. 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.
Tsuas yog li ntawd, ob lub luag haujlwm tseem ceeb ntawm qhov ntxhib endoplasmic reticulum yog dab tsi?
Qhov ntxhib ER, kawm nrog ntau lab ntawm daim nyias nyias khi ribosomes, koom nrog kev tsim khoom, folding, kev tswj kom zoo thiab xa tawm ntawm qee qhov cov protein . Smooth ER feem ntau cuam tshuam nrog lipid (rog) kev tsim khoom thiab cov metabolism thiab cov tshuaj steroid tsim cov tshuaj hormone ntau lawm. Nws kuj tseem muaj lub luag haujlwm tshem tawm cov co toxins.
Ib yam li ntawd, qhov ntxhib ER ua cov protein li cas? Raug ER hu ua ntxhib vim nws muaj ribosomes txuas rau nws nto. Ob daim nyias nyias ntawm du thiab lus ER daim ntawv hnab hu ua cisternae. Cov protein cov lwg me me tau muab coj los ua ke thiab sau rau hauv qhov cisternal space/lumen. Thaum txaus cov protein tau muab coj los ua ke, lawv khaws thiab muab pinched tawm hauv vesicles.
Tom qab ntawd, lo lus nug yog, yuav muaj dab tsi tshwm sim yog tias ER ntxhib tsis ua haujlwm?
Yog tsis muaj RER lub xovtooj ntawm tes tsis tuaj yeem tsim cov plasma membrane proteins tshiab, lysosomal enzymes, proteines rau Golgi apparatus thiab proteins rau extracellular secretion. Vim tias cov protein zoo li no tau sib sau ua ke hauv RER. Thaum tsis muaj cov txheej txheem cellular no ntawm tes yuav zaum tuag.
Lub luag haujlwm ntawm ER yog dab tsi?
Kev ua haujlwm ntawm Endoplasmic Reticulum ( ER ) Nws yog lub luag haujlwm tseem ceeb rau kev thauj cov protein thiab lwm cov carbohydrates mus rau lwm lub organelle, uas suav nrog lysosomes, Golgi cov cuab yeej, cov ntshav ntshav, thiab lwm yam.
Pom zoo:
Dab tsi ua ntxhib endoplasmic reticulum Golgi cov cuab yeej thiab lysosomes muaj ib qho?
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
Dab tsi organelles qhov ntxhib endoplasmic reticulum ua haujlwm nrog?
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
Dab tsi yog qhov txawv ntawm ER ntxhib thiab du ER Dab tsi yog ER ua qhov sib txawv hauv txhua kis?
Ob qho tib si du thiab ntxhib endoplasmic reticulum pab hauv kev tsim thiab khaws cov proteins Qhov sib txawv tseem ceeb yog tias ib qho muaj ribosomes rau nws thiab lwm yam tsis. Rough ER zoo li cov nplooj ntawv. RER sib sau ua (ua) thiab ntim cov protein. RER tau txuas nrog lub nuclear membrane
Dab tsi yuav ntxhib endoplasmic reticulum nyob hauv tsev?
Endoplasmic reticulum (ER) yog qhov uas cov lipid sib piv ntawm cov cell membrane tau sib sau ua ke, nrog rau cov protein thiab lwm yam khoom siv. Rough ER muaj cov ribosomes nto. Tus du ER tsis muaj ribosomes saum npoo. Lub qhov rooj hauv ib lub tsev zoo li lub cell membrane
Koj yuav tsum nco ntsoov dab tsi thaum siv kev hloov ntxhib?
Koj yuav tsum nco ntsoov ib txwm thaum koj siv qhov hloov pauv ntxhib los siv tsom tsom tsom iav tab sis tsuas yog siv nws nrog lub hom phiaj lub zog qis. Nyob rau hauv dab tsi koj yuav kho lub diaphragm?
