Lub endoplasmic reticulum zoo li ib lub cev nrog cov kab noj hniav uas tsim cov kab noj hniav, cov cisterns tiaj tus thiab tsis yog lamellar, cov qauv puag ncig.
Vim li cas endoplasmic reticulum zoo li pob?
Kev piav qhia: Qhov ntxhib endoplasmic reticulum (ER) yog hu ua ' ntxhib' vim nws muaj organelles hu ua ribosomes txuas rau saum npoo. Ribosomes yog cov organelles uas hloov mRNA rau hauv cov proteins. Cov proteins no yog thawj cov hlua ntev ntawm cov amino acids.
endoplasmic reticulum qauv yog dab tsi?
Lub endoplasmic reticulum (ER) yogloj, dynamic qauv uas ua haujlwm ntau lub luag haujlwm hauv lub xovtooj nrog rau calcium cia, protein synthesis thiab lipid metabolism. Cov haujlwm sib txawv ntawm ER yog ua los ntawm cov npe sib txawv; muaj cov tubules, nplooj ntawv thiab lub hnab ntawv nuclear.
Tus yam ntxwv tseem ceeb ntawm endoplasmic reticulum yog dab tsi?
Cov yam ntxwv ntawm endoplasmic reticulum yog raws li hauv qab no:
- Nws yog ib qho organelle uas tuaj yeem pom hauv cov hlwb eukaryotic.
- Cov organelles tsim ib qho kev sib txuas ntawm kev sib txuas ntawm flattened, hnab los yog raj zoo li cov qauv hu ua cisternae.
- Lub endoplasmic reticulum pab tsim lub cev pob txha.
Dab tsi yog endoplasmic reticulum thiab nws txoj haujlwm yog dab tsi?
Lub endoplasmic reticulum (ER) yog cov kab mob loj tshaj plaws hauv cov kab mob hauv eukaryotic hlwb thiab ua ntau yam haujlwm tseem ceeb ntawm tes, suav nrog protein synthesis thiab ua, lipid synthesis, thiab calcium (Ca 2+) cia thiab tso.
