Cov phospholipid bilayer phospholipid bilayer Cov kab mob lom neeg muaj cov txheej txheem txuas ntxiv ntawmlipid molecules nyob rau hauv uas membrane proteins yog embedded. Cov lipid bilayer no yog cov kua dej, nrog rau ib tus neeg lipid molecules tuaj yeem nthuav tawm sai sai hauv lawv tus kheej monolayer. Lub membrane lipid molecules yog amphipathic. Feem ntau yog cov phospholipids. https://www.ncbi.nlm.nih.gov › books › NBK26871

- lub hauv paus structural unit ntawm biomembranes - yog qhov tseem ceeb impermeable rau feem ntau dej-soluble molecules, xws li qabzib thiab amino acids, thiab rau ions. Kev thauj mus los ntawm cov molecules thiab ions hla tag nrho cov cellular daim nyias nyias yog kho los ntawm kev thauj cov proteins cuam tshuam nrog lub hauv paus bilayer.
Dab tsi yog qhov tsis tuaj yeem nkag rau dej?
Ascending limb of loop of Henle is impermeable to water. Ntawm no cov dej tsis reabsorbed, es sodium, poov tshuaj, magnesium thiab chloride reabsorbed thiab yog li ntawd cov filtrate ua hypotonic rau ntshav plasma.
Qhov twg ntawm lub voj ntawm Henle tuaj yeem nkag mus rau dej?
Ntxoov ntxoo ntawm lub voj ntawm Henle yog permeable rau dej. Dej diffuses rau hauv hyperosmolar medullary interstitium.
Yuav ua li cas ntawm DCT?
Lub luag haujlwm ntawm DCT thaum ntxov yog kev nqus ntawm ions, suav nrog sodium, chloride thiab calcium. … Cov sodiumconcentration gradient generated tso cai rau sodium nkag mus rau hauv lub cell los ntawm lub lumen ntawm lub distal convoluted tubule, uas tshwm sim los ntawm NCC symporter (sodium-chloride cotransporter), nrog rau chloride ions.
Puas yog qhov sib npaug ntawm cov tubule permeable rau dej?
Raws li ALH tsis permeable rau dej, yuav muaj qhov nce hauv peritubular capillary osmolality. Thaum lub peritubular capillary los rau hauv kov nrog tus nqis nqis ntawm Henle (uas yog permeable rau dej), cov dej yuav ntws mus rau hauv peritubular capillary lumen tom qab osmolality gradient!

Cov kab kab kab kab kab ua kab mob txaus ntshai npaum li cas?
Nyob rau hauv peb thiab tom ntej instars ntawm lawv txoj kev loj hlob, Pine processionary caterpillars yog mob heev rau daim tawv nqaij ntawm tib neegthiab lwm yam tsiaj. Kev sib cuag yooj yim nrog cov plaub hau ntawm kab ntsig tuaj yeem ua rau pob khaus hnyav (urticaria) thiab khaus qhov muag, thiab qee tus neeg yuav muaj kev fab tshuaj.
Vim li cas cov neeg ua pa tsis tuaj yeem nkag mus rau hauv tsev hais plaub?
Txawm hais tias cov txiaj ntsig ntawm kev sim ua los ntawmlub tshuab nqus pa nqus tsis tuaj yeem nkag mus rau hauv tsev hais plaub, cov kws lij choj feem ntau muaj cov tub ceev xwm ua pov thawj tias lawv tau muab tus neeg foob mus kuaj ua pa portable thiab raug ntes.
Thaum cov kab mob kab mob nkag mus rau hauv cov hlab ntsha?
Kev kis kab mob nrog cov kab mob tsis tas ua rau kab mob. Kev kis kab mob tshwm sim thaum cov kab mob, kab mob, lossis lwm yam kab mob nkag mus rau hauv koj lub cev thiab pib sib kis. Kab mob tshwm sim thaum cov hlwb hauv koj lub cev puas lawm vim yog kis kab mob thiab cov tsos mob thiab cov tsos mob tshwm sim.
Nyob hauv cell h5 nkag mus rau tus qauv uas sib npaug?
Txhawm rau ua kom yooj yim tshaj qhov sib npaug hauv Excel, ntaus qhov sib npaug kos npe (=) hauv ib lub xovtooj, tom qab ntawd ntaus thawj tus lej koj xav muab faib, ua raws li lub hnub qub, ua raws li tus lej thib ob, thiab ntaus tus yuam sij Enter los suav cov qauv.
Cov qauv tuaj yeem nkag mus rau qhov twg?
Qhov chaw nyob ntawm tus neeg siv Templates Folder tseem nyob C:\Users\ username \AppData\Roaming\Microsoft\Templates. Tus neeg siv Templates nplaub tshev tseem yuav muaj qhov qub. dotm qauv. Qhov chaw ntawm cov ntawv tais ceev tseg tuaj yeem hloov kho (lossis nrhiav pom) siv Cov Ntaub Ntawv ->
