-Plowe: Janet Plowe yog ib tug paub zoo botanist uas pab nrhiav pom cov cell membrane. Nws kuj nrhiav tau qhov elasticity thiab muaj pes tsawg leeg ntawm ntau yam cell organelle. Nws tau sau lo lus plasmalemma hauv xyoo 1931.
Leej twg nrhiav tau cell membrane?
Nyob rau thaum ntxov 1660s, Robert Hooke tau ua nws thawj zaug kev soj ntsuam siv lub teeb lub teeb. Xyoo 1665, nws tau tshuaj xyuas ib daim kab mob fungus nyob rau hauv lub teeb pom kev zoo thiab nws hu ua txhua qhov chaw ua "cellula". Nws tsis tuaj yeem pom cov cell membranes nrog lub teeb pom kev zoo uas nws siv hauv txoj kev tshawb no.
Leej twg muab tus qauv qhaub cij?
Charles Overton yog thawj tus qhia tias cov cell membrane yog tsim los ntawm lipids. Nws qhia qhov no thaum nws pom tias cov khoom uas lipid-soluble nkag mus rau hauv lub cell sai dua li cov khoom uas yog dej-soluble. Tom qab ntawd Gorter thiab Grendel tau tawm tswv yim tias lub xov tooj ntawm tes muaj ob txheej ib yam li cov qhaub cij.
Vim li cas Danielli thiab davson qauv hu ua qhaub cij?
Danielli thiab Davson, tau thov ib tus qauv, hu ua qauv qhaub cij, rau cov qauv membrane uas cov lipid bilayer tau coated ntawm nws ob sab nrog hydrated proteins (globular proteins) … electrostatic los yog van der Waals daim ntawv cog lus tuaj yeem khi lwm pab pawg rau sab nrauv protein.

Ntawm yog txoj haujlwm ntawm cov cell membrane?
Lub cell membrane, yog li ntawd, muaj ob lub luag haujlwm: thawj, ua qhov cuam tshuam khaws cov khoom ntawm cov cell hauv thiab tsis xav tau cov khoom tawmthiab, thib ob, ua lub rooj vag tso cai thauj mus rau hauv lub cell ntawm cov as-ham tseem ceeb thiab txav los ntawm lub cell ntawm cov khoom pov tseg .
