Nws lub ntsiab kev ua haujlwm yog cov synthesis ntawm lipids, steroid hormones, detoxification ntawm teeb meem metabolic byproducts thiab cia thiab metabolism ntawm calcium ions nyob rau hauv lub cell. Cov zoo ER yog txawv los ntawm lwm qhov chaw ntawm lub endoplasmic reticulum los ntawm qhov tsis muaj ribosomes membrane-bound.
Ib yam li ib tus tuaj yeem nug, dab tsi yog lub luag haujlwm tseem ceeb ntawm qhov kawg endoplasmic reticulum?
Definition ntawm Smooth ER Cov smooth endoplasmic reticulum , los yog zoo ER , yog organelle pom nyob hauv ob qho tib si tsiaj txhu thiab cov cell cog. Organelle yog ib chav nyob hauv ib lub xovtooj uas muaj qhov tshwj xeeb muaj nuj nqi . Cov Lub luag haujlwm tseem ceeb ntawm tus du ER yog ua cov khoom lag luam ntawm tes zoo li cov tshuaj hormones thiab lipid.
Dab tsi yog qhov ua haujlwm ntawm SER thiab RER? SER sawv rau smooth 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.
Ntxiv mus, dab tsi yog tus qauv ntawm cov endoplasmic reticulum du?
Smooth endoplasmic reticulum (SER), meshwork ntawm zoo disklike tubular membrane vesicles, ib feem ntawm daim nyias nyias tas li 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
Dab tsi yog qhov du endoplasmic reticulum zoo li hauv lub neej tiag tiag?
Golgi cov cuab yeej hloov kho, xaiv, thiab xa cov protein los ntawm kev muag. A lub neej tiag piv txwv rau no organelle yuav yog ib lub chaw xa ntawv. Cov Smooth Endoplasmic Reticulum yog xav txog du vim nws du tsos. Cov smooth endoplasmic reticulum Nws yog lub luag haujlwm rau lipid synthesis.

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
Puas yog qhov endoplasmic reticulum pom nyob hauv cov nroj tsuag lossis tsiaj txhu?
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
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
