A buffer yog ib qho txheej txheem uas tiv thaiv kev hloov pauv hauv pH. Lub cev tsis muaj zog siv ncaj qha tshem tawm cov kua qaub, cov hauv paus, lossis carbon dioxide los ntawm lub cev txhawm rau kho cov kab mob acidity.
Yuav ua li cas tswj pH sai tshaj plaws?
Cov pa roj carbonic acid-bicarbonate buffer system yog qhov nrawm tshaj plaws ntawm tag nrho cov txheej txheem them nyiaj.
Puas yog lub plab zom mov puas yog lub cev tsis muaj zog?
Ib lub cev tsis muaj zog yog lub cev, uas yog lub plab zom mov, uas tswj cov pH los ntawm kev tswj lub cev cov kua qaub, cov hauv paus, lossis CO2. Lub raum tubules secrete H + rau hauv cov kua dej tubular, uas feem ntau ntawm nws khi rau bicarbonate, ammonia, thiab phosphate buffers.
Dab tsi yog cov tshuaj tsis zoo hauv lub cev?
Peb lub cev tsis zoo ntawm peb lub cev yog carbonic acid bicarbonate buffer system, phosphate buffer system thiab protein buffer system.
Dab tsi yog qhov tseem ceeb tshaj plaws ntawm lub cev tsis sib xws?
Cov kab mob bicarbonate tsis zoo yog thawj qhov tsis sib xws rau ECF.

Dab tsi yog cov cuab yeej ntawm cov khoom uas tiv thaiv kev hloov pauv hauv kev txav?
Inertia yog qhov nyiam ntawm ib yam khoom los tiv thaiv kev hloov hauv nws lub xeev ntawm kev txav. … Yog li, inertia tuaj yeem raug rov txhais raws li hauv qab no: Inertia=nyiam ntawm ib yam khoom los tiv thaiv kev hloov hauv nws qhov nrawm .
Cov txheej txheem twg yog txheej txheem gradational?
Gradational processes Weathering=breakdown of material in place Gradation=leveling of land degradation (erosion)=tshem tawm highs transport=txav ntawm cov khoom aggradation (deposition)=filling in lows Tectonic txheej txheem tsim los ntawm roughen lub ntiaj teb Gradational rog theem tawm highs thiab sau nyob rau hauv lows … Qhov twg ntawm cov txheej txheem hauv qab no yog cov txheej txheem gradational?
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Puas yog txheej txheej txheej txheem siv los siv?
Kev txhim kho lub koom haum (OD) yog txheej txheej txheej txheem rau kev siv cov kev npaj hloov pauv kom ua rau tib neeg thiab cov koom haum ua tau zoo . Puas yog ib qho kev coj cwj pwm teb rau qhov tiag? Kev coj cwj pwm ntawm qhov kev xav ntawm kev xav yog qhov qhia tau tseeb ntawm kev xav.
Puas yog dna methylation ib qho kev hloov pauv hloov pauv?
Methylation yog qhov sib ntxiv ntawm pawg methyl mus rau lysine sab saw lub luag haujlwm rau chromatin transcription ua haujlwm xeev. Sulfation yog ib qho kev hloov pauv mus tas li xav tau rau kev ua haujlwm ntawm cov protein. … Kev ua kom huv ntawm cov protein hloov tom qab hloov pauv yog xav tau .
