Lub endoplasmic reticulum (ER) yog ib qho kev sib txuas txuas txuas ntxiv uas tsim cov hnab ntim sib luag nyob rau hauv cytoplasm ntawm eukaryotic hlwb. Txhua lub hlwb eukaryotic muaj ER.
Cov endoplasmic reticulum pom cov nroj tsuag lossis tsiaj nyob qhov twg?
Endoplasmic reticulum yog ib qho organelle pom nyob rau hauv ob qho tib si eukaryotic tsiaj thiab cog hlwb. Nws feem ntau tshwm raws li ob qho kev sib txuas sib txuas, uas yog ntxhib ER thiab ER du. Ob qho tib si muaj cov membrane kaw, interconnected flattened hlab.
Dab tsi yog endoplasmic reticulum pom nyob rau hauv?
Lub endoplasmic reticulum muaj nyob rau hauv feem ntau eukaryotic hlwb thiab tsim ib qho kev sib txuas sib txuas ntawm flattened, membrane-enclosed sacs hu ua cisternae (nyob rau hauv RER), thiab tubular lug nyob rau hauv lub SER. Cov membranes ntawm ER yog txuas ntxiv nrog rau sab nraud nuclear membrane.
Dab tsi ntawm tes yog qhov ntxhib endoplasmic reticulum pom hauv?
Rough endoplasmic reticulum (RER), series ntawm cov hnab ntim sib txuas, ib feem ntawm cov kab mob sib txuas txuas ntxiv nyob rau hauv lub cytoplasm ntawm eukaryotic hlwb, uas ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov proteins.
YPuas yog endoplasmic reticulum pom nyob rau hauv tib neeg?
Kev ua haujlwm ntawm endoplasmic reticulum. Lub ER paub txog ua haujlwm ntau lub luag haujlwm hauv tib neeg lub hlwb (Schwarz DS li al. … Ib qho ntawm cov haujlwm tseem ceeb ntawm ER yog kev txhais lus ntawm mRNA rau qee pawg ntawm cov protein, suav nrog cov proteins zais cia thiab Cov kab mob sib xyaw ua ke ntawm cov protein, tab sis kuj muaj qee cov cytosolic proteins.
