Kev nce cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv kab mob tso cai rau cov tshuaj tiv thaiv ntau dua muaj txiaj ntsig , thiab yog li ntau cov khoom yog generated ntawm tus nqi nrawm dua. Qhov no yog lub npe hu ua catalytic efficiency ntawm cov enzymes , uas, los ntawm kev nce tus nqi, ua rau ntau dua muaj txiaj ntsig tshuaj tiv thaiv nyob rau hauv ib tug biological system.
Hauv qhov no, tus nqi kinetic twg txhais tau tias kev ua haujlwm ntawm enzyme?
Specificity constant.), yog ib qho kev ntsuas ntawm qhov ua tau zoo npaum li cas enzyme converts substrates rau hauv cov khoom. Ib qho kev sib piv ntawm qhov tshwj xeeb tsis tu ncua kuj tuaj yeem siv los ntsuas qhov kev nyiam ntawm ib qho enzyme rau txawv substrates (piv txwv li, substrate specification).
Kuj Paub, dab tsi yog qhov cuam tshuam ntawm enzyme concentration ntawm kev ua enzyme? Los ntawm kev nce cov enzyme concentration , qhov siab tshaj plaws cov tshuaj tiv thaiv zoo heev nce. Cov ntsiab lus: Tus nqi ntawm cov tshuaj tiv thaiv kab mob nce raws li cov substrate concentration nce. Enzymes tuaj yeem ceev tus nqi ntawm cov tshuaj tiv thaiv. Txawm li cas los xij, cov enzymes ua saturated thaum lub substrate concentration yog siab.
Tsis tas li ntawd, vim li cas cov duab ntawm ib qho enzyme tseem ceeb?
Cov lub cev ntawm ib qho enzyme yog heev tseem ceeb vim nws muaj kev cuam tshuam ncaj qha rau nws li cas catalyzes cov tshuaj tiv thaiv. Ib enzyme lub cev yog txiav txim los ntawm ib theem ntawm cov amino acids nyob rau hauv nws cov qauv, thiab cov bonds uas tsim ntawm cov atoms ntawm cov molecules.
Dab tsi yog qhov ceev tshaj plaws enzyme?
Carbonic anhydrase

Nws txhais li cas rau qhov zoo ntawm ob qho tib si polygenic thiab multifactorial?
Nws yog qhov zoo uas qhia txog kev ua haujlwm ntawm ntau tshaj ib lub noob thiab tsis cuam tshuam los ntawm ib puag ncig. Piv txwv li: qhov siab, daim tawv nqaij xim, lub cev hnyav, mob, tus cwj pwm. multifactorial- ob leeg tib-gene thiab polygenic zoo tuaj yeem yog qhov no. Nws txhais tau tias lawv raug cuam tshuam los ntawm ib puag ncig
Lub Tuam Tsev txhais li cas thaum nws hais tias kuv ntseeg tias qhov zoo rau nyuj yog qhov zoo rau kev lag luam?
Lub tuam tsev txhais tau hais tias yog cov nyuj muaj kev hwm thiab kho tau zoo, lawv yuav yooj yim dua los tuav uas yuav ua rau cov txheej txheem zoo dua rau txhua tus neeg koom tes
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Nws txhais li cas kom muaj kev sib raug zoo tsis zoo?
Ib qho kev sib raug zoo tsis zoo txhais tau hais tias muaj kev sib raug zoo ntawm ob qhov sib txawv - thaum ib qho sib txawv, qhov sib txawv nce. Lub vice versa yog qhov tsis zoo correlation ib yam nkaus, nyob rau hauv uas ib tug kuj nce mus nce los thiab lwm yam txo
