Cov kua dej mosaic qauv ntawm cov plasma membrane: Cov kua dej mosaic qauv ntawm cov plasma membrane piav txog cov plasma membrane li ua kua ua ke ntawm phospholipids, cholesterol, thiab proteins… los yog dej-hlub thaj chaw ntawm cov molecules yog nyob rau hauv kev sib cuag nrog cov dej aqueous ob sab hauv thiab sab nraum cell.

Cov kua dej mosaic qauv ntawm cov plasma membrane yog dab tsi?

Cov kua dej mosaic piav qhia lub cell membrane ua ib daim kab xev ntawm ntau hom molecules (phospholipids, cholesterols, thiab proteins) uas txav mus tas li Qhov kev txav no pab cov cell membrane tswj. nws lub luag hauj lwm raws li ib tug barrier ntawm sab hauv thiab sab nraum ntawm lub cell ib puag ncig.

Vim li cas cov ntshav plasma tau piav qhia tias yog cov kua dej mosaic?

Kev piav qhia: Nws yog qee zaum hu ua cov kua dej mosaic vim nws muaj ntau hom molecules uas ntab raws li cov lipids vim muaj ntau hom molecules uas tsim cov cell membrane Piv txwv li, muaj ntau hom proteins nyob rau hauv daim nyias nyias.

Qhov twg hauv qab no piav qhia txog cov qauv ntawm cov kua dej mosaic qauv ntawm daim nyias nyias?

Cov qauv dej mosaic piav qhia cov qauv ntawm cov plasma membrane raws li cov 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.

Leej twg piav qhia cov kua dej mosaic qauv ntawm plasma membrane?

Cov kua dej mosaic qauv ntawm cov ntshav plasma membrane tau thov los ntawm the S. J. Singer thiab Garth L. Nicolson xyoo 1972. 2.
