Enzyme Reactivity. Kev sib tsoo ntawm tag nrho cov molecules nce raws li kub nce . Qhov no ua rau ntau molecules ncav cuag lub zog ua kom muaj zog, uas nce tus nqi ntawm cov tshuaj tiv thaiv. Txij li thaum cov molecules tseem txav nrawm dua, kev sib tsoo ntawm cov enzymes thiab substrate kuj nce.
Tom qab ntawd, ib tus tuaj yeem nug, vim li cas cov enzymes denature ntawm qhov kub thiab txias?
Kub siab dua cuam tshuam cov duab ntawm qhov chaw nquag, uas yuav txo nws txoj haujlwm, lossis tiv thaiv nws los ntawm kev ua haujlwm. Cov enzyme yuav tau denatured . Enzymes yog li ntawd ua haujlwm zoo tshaj plaws ntawm ib qho tshwj xeeb kub . Cov enzyme , suav nrog nws qhov chaw nquag, yuav hloov cov duab thiab lub substrate tsis haum.
Kuj Paub, vim li cas qee cov tshuaj biochemical ua rau qeeb ntawm qhov kub siab dua? Raws li cov enzyme molecules ua saturated nrog substrate, qhov no nce nyob rau hauv tshuaj tiv thaiv tus nqi qib tawm. Ntawm kub dua , cov protein yog denatured, thiab tus nqi ntawm cov tshuaj tiv thaiv txo qis heev. Ib qho enzyme muaj qhov zoo tshaj pH ntau yam uas nws nthuav tawm cov haujlwm siab tshaj plaws.
Tom qab ntawd, vim li cas cov enzymes tsis tuaj yeem ua haujlwm ntawm qhov kub thiab txias?
Yog vim li cas ntau cov enzymes kev ua si yog nyob ntawm nws cov duab, kub kev hloov tuaj yeem cuam tshuam cov txheej txheem thiab cov enzyme yuav tsis ua haujlwm . Siab txaus kub yuav ua rau enzyme mus rau denature thiab muaj nws cov qauv pib tawg. Activators ua enzymes ua haujlwm nyuaj thiab sai dua.
Yuav ua li cas thaum enzymes kub dhau?
Qhov kub thiab txias nce kev ua haujlwm molecular, thiab tuaj yeem ua rau muaj kev sib tsoo ntawm ntau dua cov enzymes thiab substrate. Yog qhov kub thiab txias ib yam nkaus siab, txawm li cas los xij, lub cov enzymes ua tau ua denatured, thiab cov txiaj ntsig zoo ntawm qhov kub thiab txias tuaj yeem ua tsis tiav.

Qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov sib faib coefficient yog dab tsi?
Ib qho inverse linear kev sib raug zoo tau pom ntawm qhov kub thiab txias thiab qhov sib faib coefficient. CEEB TOOM: Nyob rau hauv ib qho kev ntsuas kub, qhov sib faib coefficients isoflurane thiab sevoflurane txo qis thaum qhov kub nce. Sevoflurane qhia tau hais tias muaj kev solubility siab hauv Oxygent (TM) piv rau isoflurane
Qhov nqus thiab tso tawm ntawm lub zog cuam tshuam li cas rau qhov kub thiab txias thaum lub sij hawm muaj tshuaj tiv thaiv?
Nyob rau hauv endothermic cov tshuaj tiv thaiv cov enthalpy ntawm cov khoom yog ntau dua cov enthalpy ntawm cov reactants. Vim tias cov tshuaj tiv thaiv tso tawm lossis nqus lub zog, lawv cuam tshuam rau qhov kub ntawm lawv ib puag ncig. Exothermic cov tshuaj tiv thaiv cua sov ua rau lawv ib puag ncig thaum cov tshuaj tiv thaiv endothermic txias rau lawv
Vim li cas thiaj muaj qhov kub thiab txias thaum lub caij nplooj ntoos hlav thiab lub caij nplooj zeeg?
Thaum lub sab qaum teb ib nrab ntawm lub ntiaj teb yog tilted mus rau lub hnub, lub sab qab teb hemisphere yog tilted. Cov neeg nyob rau yav qab teb hemisphere tau ntsib lub hnub luv luv thiab txias dua ntawm lub caij ntuj no. Thaum lub caij nplooj zeeg thiab caij nplooj ntoos hlav, qee qhov chaw hauv ntiaj teb muaj kev zoo sib xws, me me, muaj xwm txheej
Qhov kev ua enzyme cuam tshuam li cas los ntawm qhov kub thiab txias?
Enzyme kev ua ub no nce thaum kub nce, thiab nyob rau hauv lem nce tus nqi ntawm cov tshuaj tiv thaiv. Qhov no kuj txhais tau tias kev ua haujlwm txo qis ntawm qhov txias dua. Tag nrho cov enzymes muaj qhov kub thiab txias thaum lawv ua haujlwm, tab sis muaj qee qhov kub uas lawv ua haujlwm zoo
Dab tsi yog qhov kev sib raug zoo ntawm qhov kub thiab txias hauv HR daim duab?
Lub hnub qub ci, lossis luminosity, nyob ntawm lub hnub qub qhov kub thiab qhov loj. Yog hais tias ob lub hnub qub muaj qhov kub thiab txias, lub hnub qub loj dua yuav luminous. Daim duab Hertzsprung-Russell (H-R) hauv qab no yog ib daim duab tawg uas qhia txog qhov ntsuas kub thiab qhov luminosities ntawm ntau lub hnub qub
