Enzymes catalyze cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom tsim nyog rau qhov tshwm sim tshwm sim. Lub molecule uas ib enzyme ua rau yog hu ua substrate . Hauv ib enzyme -mediated cov tshuaj tiv thaiv, substrate molecules hloov, thiab cov khoom tsim.
Hauv qhov no, lub hom phiaj ntawm enzyme catalysis lab yog dab tsi?
Cov lub hom phiaj ntawm no lab yog tshawb xyuas qhov cuam tshuam ntawm qhov kub thiab txias, substrate concentration, enzyme concentration, thiab muaj ib tug inhibitor ntawm kev ua tau zoo thiab tus nqi ntawm ib enzyme . Yog hais tias lub concentration ntawm cov enzyme los yog substrate yog nce, tus nqi ntawm cov tshuaj tiv thaiv yuav nce ntxiv.
Ib yam li ntawd, lub substrate nyob rau hauv lub siab enzyme lab yog dab tsi? Enzymes yog catalysts, uas tuaj yeem pom hauv ntau lub hlwb. Hauv kev sim, peb kawm txog kev tawg ntawm 6% hydrogen peroxide rau hauv dej thiab cov pa oxygen. Peb siv cov nqaij nyuj nyoos daim siab saib yuav ua li cas cov hydrogen peroxide ( substrate thiab catalase ( enzyme ) yuav cuam tshuam qhov kub ntawm tus nqi ntawm cov tshuaj tiv thaiv.
Tsuas yog li ntawd, dab tsi yog qhov substrate hauv kev sim?
Cov reactants ntawm enzyme Cov tshuaj tiv thaiv catalyzed hu ua substrates. Lub active site ntawm ib enzyme paub, confines, thiab orients lub substrate nyob rau hauv ib qho kev taw qhia. Enzymes yog substrate tshwj xeeb, txhais tau hais tias lawv catalyze tsuas yog cov tshuaj tiv thaiv tshwj xeeb.
Dab tsi cuam tshuam rau enzyme kev ua haujlwm lab?
Ob peb yam cuam tshuam tus nqi uas enzymatic Cov tshuaj tiv thaiv pib - kub, pH, enzyme concentration, substrate concentration, thiab muaj cov inhibitors lossis activators.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov ua haujlwm ntawm enzyme topoisomerase hauv DNA replication quizlet?
Cais cov strands los ntawm kev paub lub hauv paus chiv keeb, rhuav tshem hydrogen bonds, thiab ua ib tug replication npuas. Lub hom phiaj ntawm topoisomerase yog dab tsi? unwinds lub resulting supercoils
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Lub substrate nyob rau hauv cov tshuaj tiv thaiv no yog dab tsi?
Nyob rau hauv biochemistry, lub substrate yog ib tug molecule raws li ib tug enzyme ua. Enzymes catalyze cov tshuaj tiv thaiv nrog rau cov substrate. Nyob rau hauv cov ntaub ntawv ntawm ib tug substrate, lub substrate bonds nrog lub enzyme active site, thiab ib tug enzyme-substrate complex yog tsim
