Cov endoplasmic reticulum ua haujlwm ntau yam dav dav kev ua haujlwm , suav nrog cov folding ntawm cov protein molecules hauv cov hnab hu ua cisternae thiab thauj cov proteins uas tsim los hauv cov hlab ntsha mus rau Golgi apparatus.
Ua raws li qhov xav tau, qhov ua haujlwm ntawm endoplasmic reticulum hauv ib lub cell yog dab tsi?
Endoplasmic reticulum ( ER ), hauv kev tshawb fawb txog biology, cov txheej txheem txheej txheej tas mus li uas tsim ua ib txheej ntawm cov hnab ntim hauv cov cytoplasm ntawm eukaryotic hlwb thiab ua haujlwm ntau yam kev ua haujlwm , yog qhov tseem ceeb tshwj xeeb hauv kev sib txuas, sib dhos, hloov kho, thiab thauj cov protein.
Kuj Paub, dab tsi yog 3 lub luag haujlwm tseem ceeb ntawm endoplasmic reticulum? Nws plays lub luag haujlwm tseem ceeb hauv kev tsim khoom, kev ua, thiab kev thauj mus los cov protein thiab lipid. ER ua cov transmembrane cov protein thiab lipids rau nws daim nyias nyias thiab ntau lwm yam ntawm tes xws li lysosomes, secretory vesicles, Golgi appatatus, cell membrane, thiab cog cell vacuoles.
Hais txog qhov no, qhov endoplasmic reticulum ua haujlwm li cas?
Endoplasmic Reticulum - Wrapping nws Up Lwm organelle hauv lub cell yog endoplasmic reticulum ( ER ). Thaum lub luag haujlwm ntawm nucleus yog ua raws li lub hlwb hlwb, lub ER ua haujlwm raws li kev tsim khoom thiab ntim khoom. Nws ua haujlwm ze nrog Golgi cov cuab yeej, ribososmes, mRNA, thiab tRNA.
Lub luag haujlwm ntawm SER thiab RER yog dab tsi?
SER sawv rau du endoplasmic reticulum uas pab tsim cov roj molecules, lossis lipid, tseem ceeb rau ntawm tes muaj nuj nqi . RER sawv rau ntxhib endoplasmic reticulum uas zoo li ntxhib nyob hauv lub tshuab tsom iav vim nws muaj cov khoom hu ua ribosomes txuas rau nws saum npoo.
Pom zoo:
Qhov ntxhib endoplasmic reticulum nyob qhov twg?
Rough ER tau pom thoob plaws hauv lub xovtooj tab sis qhov ntom tau siab dua nyob ze cov nucleus thiab cov cuab yeej Golgi. Ribosomes ntawm qhov ntxhib endoplasmic reticulum hu ua 'membrane bound' thiab yog lub luag haujlwm rau kev sib dhos ntawm ntau cov protein. Txoj kev no hu ua kev txhais lus
Dab tsi yog qhov ua haujlwm ntawm endoplasmic reticulum rau menyuam?
Endoplasmic reticulum yog sau los ntawm cov raj uas ua, pob, thiab thauj cov protein thiab cov rog. Rough endoplasmic reticulum muaj protein-ua ribosomes ntawm nws qhov chaw, yog li nws pab ua thiab txheej txheem cov protein. Qhov kawg endoplasmic reticulum pab ua thiab txheej txheem lipid thiab pab tshem tawm cov tshuaj thiab dej cawv
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 lub luag haujlwm tseem ceeb ntawm du endoplasmic reticulum ER?
Nws lub luag haujlwm tseem ceeb yog kev sib txuas ntawm cov lipid, cov tshuaj steroid, kev tshem tawm cov teeb meem metabolic los ntawm cov khoom lag luam thiab kev khaws cia thiab cov metabolism hauv calcium ions hauv lub cell. ER du yog qhov txawv ntawm lwm qhov ntawm endoplasmic reticulum los ntawm qhov tsis muaj daim nyias nyias-khi ribosomes
Dab tsi yog qhov ua haujlwm ntawm endoplasmic reticulum du?
Nws lub luag haujlwm tseem ceeb yog kev sib txuas ntawm cov lipid, cov tshuaj steroid, kev tshem tawm cov teeb meem metabolic los ntawm cov khoom lag luam thiab kev khaws cia thiab cov metabolism hauv calcium ions hauv lub cell. ER du yog qhov txawv ntawm lwm qhov ntawm endoplasmic reticulum los ntawm qhov tsis muaj daim nyias nyias-khi ribosomes
