Dialysis tubing yog ib qho khoom siv semi-permeable daim nyias nyias nrog cov khoom zoo sib xws rau lub cell daim nyias nyias.
Kuj nug, puas yog dialysis tubing yog tus qauv zoo ntawm lub cell membrane?
Plasma membrane ntawm a cell tuaj yeem ua qauv ntau yam, tab sis dialysis tubing tshwj xeeb yog pab tau rau qauv yam tshuaj twg yuav diffuse los yog raug thauj tawm ntawm ib cell membrane.
Ib tug kuj yuav nug, dab tsi yog qhov tshwj xeeb txog kev lim ntshav tubing? Dialysis tubing , tseem hu ua Visking cev , yog ib qho khoom siv semi-permeable tubing lub cev siv nyob rau hauv kev sib cais cov tswv yim, uas pab txhawb cov ndlwg ntawm me me molecules nyob rau hauv kev daws raws li qhov sib txawv diffusion.
Tom qab ntawd, lo lus nug yog, yuav ua li cas lim ntshav tubing ua lub semipermeable membrane?
Qhov no dialysis tubing yog xaiv permeable regenerated cellulose siv los ua kom pom cov hauv paus ntsiab lus ntawm osmosis thiab diffusion. Pores hauv daim nyias nyias tso cai rau cov dej, feem ntau ions, thiab me me molecules. Cov khoom hnyav molecular hnyav xws li cov hmoov txhuv nplej siab, polysaccharides, rog thiab protein raug txwv.
Qhov twg ntawm lub xov tooj ntawm tes ua lub tshuab lim dej sawv cev?
Hauv koj cell model: ua dialysis tubing sawv cev lub " cell daim nyias nyias ” • Cov ntsiab lus ntawm lub hnab sawv cev “ cell cov cytoplasm." • Qhov chaw sab nraum lub hnab sawv cev lub " cell cov ib puag ncig."

Puas yog glycerol xav tau daim nyias nyias nyias kom hla daim nyias nyias?
Glycerol yog lipid soluble yog li nws diffuses los ntawm yooj yim diffusion ncaj qha los ntawm lub cell membrane thaum cov piam thaj yog ib tug polar molecule yog li nws diffuses los ntawm kev yooj yim diffusion uas txhais tau hais tias nws xav tau ib tug channel protein ua hauj lwm thiab qhov no txhais tau tias thaj chaw saum npoo rau cov piam thaj kom nkag mus yog tsawg dua. tshaj ib qho rau glycerol
Dab tsi yog ib qho laj thawj uas ib lub xovtooj yuav tsum tau tswj cov dej ntws hla ntawm daim nyias nyias?
Dab tsi yog ib qho laj thawj uas lub cell yuav tsum tswj cov flowacross daim nyias nyias? Lub nucleus yuav tsum coj mus rau hauv DNA. Lub cell xav tau cov pa roj carbon dioxide ua lub zog. Cov cytoplasmneeds coj cov organelles
Dab tsi yog cov haujlwm sib txawv ntawm daim nyias nyias?
Kev ua haujlwm ntawm Membrane Proteins Membrane proteins tuaj yeem ua haujlwm ntau yam haujlwm tseem ceeb: Kev sib tshuam - Ua haujlwm txuas thiab koom nrog ob lub hlwb ua ke. Enzymes - Kho rau daim nyias nyias localises metabolic txoj kev. Tsheb thauj mus los - Lub luag haujlwm rau kev yooj yim diffusion thiab nquag thauj
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Lub luag haujlwm ntawm daim nyias nyias thauj proteins yog dab tsi?
Kev thauj cov proteins ua lub qhov rooj rau ntawm tes, pab qee cov molecules hla rov qab mus rau hauv cov plasma membrane, uas nyob ib puag ncig txhua lub cell. Nyob rau hauv passive thauj molecules txav los ntawm ib cheeb tsam ntawm siab concentration mus rau qhov chaw uas tsis muaj concentration
