Rough ER nyob tam sim ntawd nyob ib sab ntawm lub cell nucleus, thiab nws daim nyias nyias yog txuas ntxiv nrog rau sab nrauv ntawm lub hnab ntawv nuclear. Cov ribosomes ntawm ntxhib ER tshwj xeeb hauv kev sib txuas ntawm cov proteins uas muaj cov teeb liab sib lawv liag uas coj lawv tshwj xeeb rau ER rau kev ua haujlwm.
Puas tuaj yeem pom ntawm endoplasmic reticulum thiab ua cov proteins?
Cov tawv nqaij endoplasmic reticulum muaj nyob rau ntawm nws ribosomes, uas yog me me, puag ncig organelles uas nws ua haujlwm yog los ua cov proteins.
Dab tsi ntawm ER synthesizes proteins?
Rough endoplasmic reticulum (RER), series ntawm kev sib txuas ntawm cov hnab ntim sib txuas, ib feem ntawm daim nyias nyias organelle nyob rau hauv lub cytoplasm ntawm eukaryotic hlwb, uas plays lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov proteins.
Pom dab tsi ntawm qhov endoplasmic reticulum?
Endoplasmic reticulum yog lub network ntawm daim nyias nyias hauv lub cell uascov protein thiab lwm cov molecules txav. Proteins tau sib sau ua ke ntawm organelles hu ua ribosomes. … Smooth endoplasmic reticulum tsis muaj ribosomes thiab pab synthesize thiab concentrate ntau yam tshuaj xav tau los ntawm lub cell.
Yuav ua li cas cov proteins yog tsim los ntawm ER ntxhib?
Proteins synthesized los ntawm ntxhib ER suav nrog prominent mis nyuj protein casein, thiab whey proteins. Cov proteins no tau ntim rau hauvsecretory vesicles los yog micelles loj thiab taug kev los ntawm Golgi network ua ntej fusing nrog plasma membrane, tso lawv cov ntsiab lus mus rau hauv cov mis nyuj ducts.

Ntawm yog txoj haujlwm ntawm endoplasmic reticulum?
Main. Lub endoplasmic reticulum (ER) yog qhov loj tshaj plaws membrane-bound organelle nyob rau hauv eukaryotic hlwb thiab ua ntau yam tseem ceeb cellular zog, xws li protein synthesis thiab ua, lipid synthesis, thiab calcium (Ca 2 + ) cia thiab tso.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Qhov twg endoplasmic reticulum ua ribosomes?
Cov tawv nqaij endoplasmic reticulum muaj nyob rau ntawm nws ribosomes, uas yog me me, puag ncig organelles uas nws ua haujlwm yog los ua cov proteins. YPuas ER ntxhib ua ribosomes? Rough endoplasmic reticulum, (RER), muaj coob tus ribosomes txuas rau sab nrauv ntawm lamella daim nyias nyias.
Cov nroj tsuag puas muaj endoplasmic reticulum?
Lub endoplasmic reticulum (ER) yog ib qho organelle uas muaj zog heev hauv eukaryotic hlwb thiab qhov chaw tsim khoom loj ntawm cov proteins destined rau vacuoles, cov plasma membrane, los yog apoplast hauv nroj tsuag. Pob nroj tsuag thiab tsiaj txhu muaj endoplasmic reticulum?
Nyob rau hauv lub cev ntawm tus txiv neej aqueduct ntawm sylvius tshwm sim nyob rau hauv?
Lub ventricles muaj plaub qhov khoob, cov kua dej puv hauv lub hlwb. … Nws txuas nrog lub paj hlwb aqueduct lossis aqueduct ntawm Sylvius hauv qhov nruab nrab ntawm lub hlwbrau plaub lub ventricle hauv pons thiab medulla. Lub aqueduct ntawm Sylvius nyob qhov twg?
