Cov qauv ntawm lipid bilayer tso cai rau me me, tsis muaj cov khoom siv xws li oxygen thiab carbon dioxide, thiab hydrophobic molecules xws li lipids, rau dhau ntawm lub cell membrane , down lawv concentration gradient, los ntawm yooj yim diffusion.

Tsis tas li ntawd, ua li cas oxygen nkag mus rau hauv lub cell membrane?

Cov pa roj carbon dioxide (CO2) thiab oxygen (O2) yog ob qho tib si molecules uas tuaj yeem txav mus los cell daim nyias nyias los ntawm qhov yooj yim diffusion. Thaum tshiab oxygen molecules nyob rau hauv koj lub ntsws tuaj cuag koj cov ntshav liab hlwb , lawv diffuse sai thoob plaws koj cov ntshav liab cell daim nyias nyias rau hauv hlwb , los yog cia lawv cov concentration gradient.

Kuj Paub, tuaj yeem oxygen diffuse los ntawm lub cell membrane? Tsuas yog me me, tsis-polar molecules, xws li oxygen thiab carbon dioxide, tau diffuse yooj yim hla tus daim nyias nyias.

Tsis tas li ntawd, muaj pes tsawg lub cell membrane puas oxygen hla dhau?

Koj tau txais tag nrho cov hlwb txoj cai, tab sis koj qhov teeb meem tsuas yog qhov no: oxygen diffuses dhau tus cell membrane nkag rau hauv cell , txav dhau tus cytoplasm , thiab diffuses dhau tus daim nyias nyias rov tawm lub cell . Yog li, rau txhua tus cell , koj yuav tsum suav 2 daim nyias nyias.

Yuav ua li cas dej hla ntawm lub cell membrane?

Dej tau kuj dhau ntawm lub cell membrane los ntawm osmosis, vim yog siab osmotic siab sib txawv ntawm sab hauv thiab sab nraud cell . Dej hla dhau Lub lipid bilayer los ntawm diffusion thiab osmosis, tab sis feem ntau ntawm nws tsiv dhau cov protein tshwj xeeb hu ua aquaporins.
