Lwm organelle nyob rau 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 cov Golgi apparatus , ribososmes, mRNA, thiab tRNA.
Kuj paub, dab tsi organelles tus du endoplasmic reticulum ua haujlwm nrog?
Smooth endoplasmic reticulum (SER), meshwork ntawm zoo disk zoo li tubular membrane vesicles, ib feem ntawm ib daim nyias nyias organelle nyob rau hauv cytoplasm ntawm eukaryotic cells, uas koom nrog hauv kev sib txuas thiab khaws cia ntawm lipid, suav nrog cov roj cholesterol thiab phospholipids, uas tau siv hauv kev tsim cov cellular tshiab
Tsis tas li ntawd, cov nucleus ribosomes ntxhib endoplasmic reticulum thiab Golgi apparatus ua haujlwm ua ke li cas? Ribosomes , cov endoplasmic reticulum thiab cov Golgi apparatus yog cuam tshuam nrog ib leeg dhau los ntawm lawv kev koom tes hauv kev tsim cov protein thiab thauj. Lub luag haujlwm tseem ceeb ntawm Golgi apparatus yog los hloov cov proteins thiab ntim lawv mus rau hauv vesicles. Los ntawm no lawv yog thauj mus rau ntau qhov chaw ntawm tes.
Tom qab ntawd, lo lus nug yog, qhov ntxhib endoplasmic reticulum ua dab tsi?
Rough endoplasmic reticulum yog organelle pom nyob hauv cov hlwb eukaryotic. Nws lub luag haujlwm tseem ceeb yog tsim 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.
Tus qauv ntawm kev ntxhib endoplasmic reticulum yog dab tsi?
Qhov ntxhib endoplasmic reticulum feem ntau yog ua los ntawm cov nplooj ntawv - ib qho kev sib txuas ntawm ob sab ntawm cov hnab ntim uas txuas mus thoob plaws cytoplasm. Ntxiv rau ribosomes , cov membranes muaj ib qho tseem ceeb ntawm cov protein complex hu ua translocon, uas yog tsim nyog rau kev txhais cov protein nyob rau hauv cov ntxhib ER.
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 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 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 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
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
