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.
