Cov endomembrane system yog ib tug series ntawm compartments uas ua hauj lwm ua ke rau pob, daim ntawv lo, thiab nkoj proteins thiab molecules. Hauv koj lub hlwb, cov endomembrane system yog tsim los ntawm ob qho tib si endoplasmic reticulum thiab Golgi apparatus. Cov ntaub ntawv no yog cov folds ntawm daim nyias nyias uas tsim cov hlab thiab cov hnab hauv koj lub hlwb.
Nyob rau hauv txoj kev no, dab tsi yog cov khoom ntawm Endomembrane system thiab nws txoj haujlwm yog dab tsi?
Lub endomembrane system muaj xws li lub hnab ntawv nuclear, cov lysosomes , cov hlab ntsha , ER, thiab Golgi apparatus , nrog rau cov plasma membrane. Cov khoom siv ntawm tes no ua haujlwm ua ke los hloov kho, pob, tag, thiab thauj cov proteins thiab lipids uas tsim cov membranes.
Tom qab ntawd, lo lus nug yog, uas tsis yog qhov ua haujlwm ntawm Endomembrane system? Hauv eukaryotes, organelles ntawm lub endomembrane system muaj xws li: nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, vesicles thiab endosomes. Hauv qhov no, nws yuav tsum tau muab sau tseg tias lub endomembrane system ua tsis yog suav nrog mitochondria, peroxisome thiab chloroplast daim nyias nyias.
Kuj nug, dab tsi yog qhov haujlwm tseem ceeb ntawm Endomembrane system?
Lub luag haujlwm tseem ceeb ntawm no qhov system yog hloov, ntim thiab thauj cov proteins thiab lipids hauv thiab tawm ntawm tes. Lub ntsiab organelles uas tsim cov endomembrane system yog - nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, thiab vesicles.
Dab tsi yog txhais los ntawm Endomembrane system?
Cov endomembrane system yog a qhov system ntawm membranous Cheebtsam. Nws suav nrog cov membranes ntawm nucleus, endoplasmic reticulum, Golgi apparatus, lysosomes, endosomes, vesicles, thiab cell membrane.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Cov organelles twg yog ib feem ntawm Endomembrane system?
Nyob rau hauv eukaryotes cov organelles ntawm lub endomembrane system muaj xws li: lub nuclear membrane, endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, endosomes, thiab plasma (cell) membrane ntawm lwm tus
Cov haujlwm ua haujlwm li cas hauv lej?
Hauv kev ua lej, kev ua haujlwm yog qhov kev sib raug zoo ntawm cov teeb tsa uas koom nrog txhua lub ntsiab lus ntawm thawj zaug raws nraim ib qho ntawm cov txheej thib ob. Cov piv txwv zoo yog cov haujlwm los ntawm cov lej mus rau cov lej lossis los ntawm cov lej tiag mus rau cov lej tiag. Piv txwv li, txoj haujlwm ntawm lub ntiaj teb yog lub luag haujlwm ntawm lub sijhawm
Vim li cas lysosomes yog ib feem ntawm Endomembrane system?
Nws rhuav tshem cov qauv qub thiab tsis tsim nyog kom lawv cov molecules tuaj yeem rov qab siv dua. Lysosomes yog ib feem ntawm cov kab mob endomembrane, thiab qee cov hlwv uas tawm hauv Golgi raug khi rau lysosome. Lysosomes kuj tuaj yeem zom cov khoom txawv teb chaws uas tau coj mus rau hauv lub cell los ntawm sab nraud
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
