Cov qauv dej mosaic piav qhia ntau yam kev soj ntsuam txog cov qauv ntawm cov cell ua haujlwm. Raws li cov qauv kev lom neeg no, muaj lipid bilayer nyob rau hauv uas cov protein molecules yog embedded. Lub lipid bilayer muab fluidity thiab elasticity rau daim nyias nyias.
dej mosaic txhais li cas?
Cov kua dej mosaic qauv piav qhia lub cell membrane ua ib daim kab xev ntawm ntau hom molecules (phospholipids, cholesterols, thiab proteins) uas niaj hnub txav. Qhov kev txav no pab cov cell membrane tuav nws lub luag haujlwm ua qhov thaiv ntawm sab hauv thiab sab nraud ntawm lub xov tooj ntawm tes.
Vim li cas lawv thiaj hu nws ua dej mosaic?
Lub sij hawm "mosaic" ntawm tus qauv no yog hais txog kev sib xyaw ntawm lipids thiab cov protein nyob hauv lub cev hauv daim nyias nyias. Cov ciam teb no kuj yog "kua dej" vim lawv cov khoom tuaj yeem txav mus tom qab, tso cai rau ob qho tib si nthuav tawm ntawm cov khoom thiab cov kev sib sau hauv zos.
Vim li cas cov kua dej mosaic yog cov kua dej thiab mosaic?
Cell daim nyias nyias yog sawv cev raws li cov kua dej-mosaic, vim qhov tseeb tias lawv yog: kua - cov phospholipid bilayer yog khov thiab ib tus neeg phospholipids tuaj yeem txav mus los . Mosaic - cov phospholipid bilayer yog embedded nrog cov proteins, ua rau cov mosaic ntawm cov khoom.
Dab tsi ua kua dej mosaic?
Cov kua dej mosaic qauv piav qhia cov qauv ntawm cov ntshav plasmaua mosaic ntawm cov khoom- suav nrog phospholipids, cholesterol, proteins, thiab carbohydrates - uas ua rau lub cev ua kua dej. Plasma daim nyias nyias muaj li ntawm 5 txog 10 nm hauv thickness.
