Los ntawm Wikipedia, dawb encyclopedia. Cotransporters yog subcategory ntawm daim nyias nyias thauj cov proteins (transporters) uas ob peb lub zog zoo ntawm ib tug molecule nrog nws concentration gradient thiab unfavorable zog ntawm lwm molecule tiv thaiv nws concentration gradient.
Hauv qhov no, Cotransport piv txwv yog dab tsi?
Ib piv txwv yog Na+/ qabzib tsheb thauj mus los (SGLT), uas ob peb lub zog ntawm Na+ Nyob rau hauv lub cell cia nws electrochemical gradient mus rau lub zog ntawm qabzib mus rau hauv lub cell tiv thaiv nws concentration gradient. Kev thauj mus los kuj feem ntau hu ua symport.
Tsis tas li ntawd, Cotransport thiab Countertransport yog dab tsi? Cotransport thiab countertransport yog ob hom kev thauj mus los thib ob. Kev thauj mus los thauj ob hom sib txawv ntawm cov molecules tib lub sijhawm hauv kev sib txuas ua ke thaum kev thauj mus los los yog pauv yog ib hom kev thauj mus los uas thauj ob hom molecules nyob rau hauv opposite direction hla lub membrane.
Ntxiv rau qhov no, vim li cas Cotransport tseem ceeb?
Cov tsheb thauj mus los yog cov twj tso kua mis protein siv los xa tawm lossis xa cov khoom me me. Electrochemical gradient rau cov tsheb thauj mus los yog vim lub zog ntawm Na + thiab H + ions. Qhov no powers lub zog ntawm lwm yam khoom uas yog pumped nyob rau hauv los yog tawm, tiv thaiv lub concentration gradient.
Puas yog Cotransport xav tau ATP?
Secondary active thauj ( kev thauj mus los ), ntawm qhov tod tes, siv electrochemical gradient - tsim los ntawm kev thauj mus los - ua lub zog los txav molecules tawm tsam lawv cov gradient, thiab yog li ua tsis ncaj qha xav tau ib tug chemical qhov chaw ntawm lub zog xws li ATP.

Koj txhais qhov hnyav txhais li cas?
Cov ntsiab lus. Weighted Mean: Ib qho txhais tau tias qee qhov txiaj ntsig pab ntau dua li lwm tus. Thaum qhov hnyav ntxiv rau 1: tsuas yog muab txhua qhov hnyav los ntawm tus nqi sib xws thiab suav tag nrho. Txwv tsis pub, muab txhua qhov hnyav w los ntawm nws qhov sib piv tus nqi x, suav tias tag nrho, thiab faib los ntawm qhov sib npaug ntawm qhov hnyav: Qhov Ntsuas Ntsuas = ΣwxΣw
Cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas thiab lawv cuam tshuam li cas?
Hydrophobic txhais tau hais tias cov molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic, txhais tau tias lawv nyob hauv daim nyias nyias. Hydrophilic txhais tau hais tias cov molecule muaj affinity rau dej
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Koj txhais li cas los ntawm lo lus txhais?
Lub ntsiab lus txhais yog ib nqe lus ntawm lub ntsiab lus ntawm ib lo lus (ib lo lus, kab lus, lossis lwm yam cim). Cov lus txhais tau muab faib ua ob pawg loj, cov ntsiab lus tsis txaus ntseeg (uas sim muab lub ntsiab lus ntawm lub ntsiab lus) thiab cov ntsiab lus txuas ntxiv (uas sim sau cov khoom uas ib lo lus piav qhia)
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
