Dab tsi yog ib qho laj thawj uas ib lub xovtooj ntawm tes yuav tsum tswj cov flowacross daim nyias nyias? Lub nucleus yuav tsum coj mus rau hauv DNA. Cov cellneeds carbon dioxide raws li lub hauv paus ntawm lub zog. Cov cytoplasmneeds coj cov organelles.

Ib yam li ntawd, nws tau nug, vim li cas kev thauj mus los ntawm cov cell membrane tseem ceeb?

Cell thauj hais txog kev txav ntawm cov khoom hla lub cell membrane . Tej zaum feem ntau tseem ceeb feature ntawm a cell cov phospholipid daim nyias nyias yog tias lawv xaiv permeable. Qhov no tso cai rau ib cell tswj cov thauj ntawm cov ntaub ntawv, raws li dictated los ntawm lub cell cov muaj nuj nqi.

Yuav ua li cas cov tshuaj txav mus thoob lub cell membrane? Dej hla dhau lub daim nyias nyias nyob rau hauv ib tug diffusion txheej txheem hu ua osmosis. Thaum lub sijhawm thauj khoom, lub zog yog siv los pab cov khoom txav hla tus daim nyias nyias nyob rau hauv adirection tiv thaiv lawv cov concentration gradient. Kev thauj mus los yuav tshwm sim nrog kev pab ntawm cov twj tso kua mis los yog los ntawm kev siv cov vesicles.

Kuj paub, dab tsi tswj kev txav ntawm cov molecules rau hauv thiab tawm ntawm lub cell?

Cov cell membrane yog selectively permeable toions thiab organic molecules thiab tswj lub zog ntawm cov khoom hauv thiab tawm ntawm hlwb . Basic function ntawm lub cell membrane yog los tiv thaiv cov cell los ntawm nws ib puag ncig. Nws muaj phospholipid bilayer nrog embeddedproteins.

Dab tsi yog tus yam ntxwv ntawm lub cell membrane?

Cov cell membrane ncig lub cytoplasm ntawm kev ua neej nyob hlwb , lub cev cais cov intracellularcomponents los ntawm extracellular ib puag ncig. Cov cellmembrane yog semi-permeable, piv txwv li, nws tso cai rau qee yam khoom siv los ntawm nws thiab tsis tso cai rau lwm tus. Cov cell membrane muaj cov ntsiab lus loj ntawm cov protein, typica
