Hauv biology, qhov chaw nquag yog thaj tsam ntawm ib qho enzyme qhov twg txheej txheej molecules khi thiab raug tshuaj lom tshuaj. Lub tsev kawm ntawv nquag muaj cov seem uas tsim cov ntawv cog lus ib ntus nrog substrate (qhov chaw sib khi) thiab cov seem uas ua rau cov tshuaj tiv thaiv ntawm qhov ntawd txheej txheej (catalytic site).
Yog li ntawd, yuav ua li cas tshwm sim thaum ib tug enzyme khi rau ib tug substrate?
Thaum ib enzyme khi nws txheej txheej , nws tsim ib qho enzyme - substrate complex. Qhov nyuaj no txo qis kev ua kom muaj zog ntawm cov tshuaj tiv thaiv thiab txhawb nws txoj kev loj hlob sai los ntawm kev muab qee yam ions lossis pab pawg tshuaj lom neeg uas tau tsim covalent bonds nrog cov molecules raws li cov kauj ruam tsim nyog ntawm cov txheej txheem kev tawm tsam.
Ib yam nkaus, nws hu ua dab tsi thaum hloov pauv cov enzyme? Induced haum Hloov, 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 ua kom nrawm tshuaj lom neeg los ntawm kev nqa ob lub substrates ua ke hauv txoj hauv kev raug.
4 yam dab tsi tuaj yeem cuam tshuam txoj kev ua haujlwm enzymes?
Muaj ntau yam cuam tshuam rau tus nqi uas cov tshuaj tiv thaiv enzymatic pib ua - kub , pH, enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.
Yuav ua li cas yog hais tias ib yam khoom uas tsis yog ib tug substrate molecule khi rau ib tug enzyme lub active site?
Thaiv qhov chaw nquag Yuav ua li cas tshwm sim yog tias cov tshuaj uas tsis yog cov txheej txheem txheej txheej khi rau ib qho enzyme qhov chaw ua haujlwm ? Digestive enzyme Enzyme kev ua haujlwm yuav qeeb. Enzyme kev ua si yuav ua kom nrawm dua. Cov enzyme yuav tawg lub yam khoom.

Lub npe feem ntau muab rau cov kua siv hauv qhov dej drilling yog dab tsi?
Emulsions: Ob hom siv yog roj hauv dej (roj av emulsion av nkos) thiab dej hauv cov roj (hloov cov roj emulsion av nkos)
Lub npe dab tsi tau muab rau Wall Street kev sib tsoo ntawm 29th Lub Kaum Hli 1929 tseem hu ua kev lag luam poob ntawm xyoo 1929 uas ua rau muaj Kev Nyuaj Siab Loj nyob rau xyoo 1930 Kev Nyuaj Siab Loj yog lub ntiaj teb loj heev
Kev Nyuaj Siab Loj tau pib hauv Tebchaws Meskas tom qab muaj kev poob loj hauv cov nqi khoom lag luam uas pib thaum lub Cuaj Hlis 4, 1929, thiab tau dhau los ua xov xwm thoob ntiaj teb nrog kev lag luam lag luam poob ntawm Lub Kaum Hli 29, 1929, (lub npe hu ua Dub Tuesday). Nyob nruab nrab ntawm 1929 thiab 1932, thoob ntiaj teb cov khoom lag luam thoob ntiaj teb (GDP) poob los ntawm kwv yees li 15%
Dab tsi ntawm cov hauv qab no yog hom kev lag luam uas tsom rau kev muab cov ntaub ntawv rau cov neeg siv sab hauv?
Kev lag luam nyiaj txiag tsom rau kev muab cov ntaub ntawv rau cov neeg siv sab hauv. cuav. (Lub hom phiaj tseem ceeb ntawm kev lag luam nyiaj txiag yog qhov tseeb kom tau txais cov ntaub ntawv rau cov neeg siv sab nraud xws li cov koom haum se, cov tswv lag luam, cov tub ua lag luam lossis cov neeg qiv nyiaj
Dab tsi yog cov txheej txheem rau kev npaj cov nyiaj hauv ib daim ntawv teev npe uas muab tus lej account thiab khaws cov ntaub ntawv tam sim no?
Kev Sau Npe Tshooj 4 Kev saib xyuas cov ntaub ntawv Crosswords A B Cov txheej txheem rau kev npaj cov nyiaj hauv ib daim ntawv teev npe dav dav, muab tus lej account, thiab khaws cov ntaub ntawv tam sim no. qhib ib tus account Sau npe tus account thiab tus lej ntawm lub npe ntawm tus account. Tshaj tawm Hloov cov ntaub ntawv los ntawm cov ntawv sau nkag mus rau ib tus account ledger
Dab tsi yog qhov txawv ntawm cov saw ntawm lub npe thiab cov ntsiab lus ntawm lub npe?
Ib daim ntawv tso cai muaj cov npe ntawm txhua tus neeg uas tau txais lub npe rau ib qho khoom. Ib txoj hlua ntawm kev tshawb nrhiav lub npe tuaj yeem nthuav tawm me me lossis loj tawg hauv cov saw hlau. Ib qho kev paub daws teeb meem ntawm lub npe suav nrog cov ntaub ntawv los ntawm deeds, mortgages, easements, and debts to provide a condensed history of the title
