Cov protein hloov puab raws li qhov kub thiab txias hloov. Yog vim li cas ntau cov enzymes kev ua si yog nyob ntawm nws puab , kub hloov ua tau mess up cov txheej txheem thiab cov enzyme yuav tsis ua haujlwm. Qib pH: Lub acidity ntawm ib puag ncig hloov cov puab ntawm cov proteins tib yam li qhov kub thiab txias.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog 3 yam uas tuaj yeem cuam tshuam txoj kev ua haujlwm ntawm enzymes?
Ob peb yam cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv enzymatic mus - kub , pH, enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.
Ib yam li ntawd, dab tsi ua rau cov enzymes rau denature? Thaum cov enzymes denature, lawv tsis ua haujlwm thiab tsis tuaj yeem ua haujlwm. Heev kub thiab qhov tsis ncaj ncees lawm ntawm pH - ib qho kev ntsuas ntawm cov tshuaj acidity lossis alkalinity - tuaj yeem ua rau cov enzymes ua denatured.
Hauv qhov no, nws hu ua dab tsi thaum lub enzyme hloov cov duab?
Induced haum Xwb, ib enzyme hloov cov duab me ntsis thaum nws khi nws cov substrate, uas ua rau ib tug txawm tighter haum. Qhov kev hloov kho ntawm lub enzyme kom snugly haum lub substrate yog hu ua induced haum. Ib txhia cov enzymes ceev cov tshuaj tiv thaiv los ntawm kev nqa ob lub substrate ua ke nyob rau hauv txoj cai orientation.
Cov qauv ntawm cov enzymes cuam tshuam li cas rau lawv txoj haujlwm?
Feem ntau cov enzymes yog cov proteins thiab yog li ntawd lawv txoj haujlwm yog tshwj xeeb rau lawv cov qauv . Cov enzyme khi nrog rau qhov tsim nyog substrate tsuas yog nyob rau hauv qhov tseeb alignment thiab orientation kom txuas cov molecules. Qhov tshwm sim enzyme -substrate complex enables cov tshuaj tiv thaiv tshwm sim.

Cov nplooj saum npoo ntawm thaj chaw cuam tshuam li cas rau kev txav ntawm cov dej los ntawm cov nroj tsuag?
Vim tias cov dej evaporates los ntawm ntau lub stomata ntawm nplooj nplooj, tus nqi ntawm transpiration yog ncaj qha cuam tshuam rau thaj chaw saum npoo
