Nws tuaj yeem sib cav RubBisCO yog feem ntau tseem ceeb enzyme vim nws yog ib qho ntawm cov enzymes ntau tshaj plaws hauv ntiaj teb. Ua los ntawm tag nrho cov nroj tsuag ntsuab, RubBisCO Nws yog lub luag haujlwm rau kho cov pa roj carbon dioxide rau hauv qhov kawg uas ua rau cov suab thaj nyuaj.
Ntxiv rau qhov no, lub hom phiaj ntawm Rubisco hauv photosynthesis yog dab tsi?
Ribulose bisphosphate carboxylase/oxygenase RUBISCO ) yog 550-kDa enzyme, cov protein ntau tshaj plaws hauv ntiaj teb, uas ua rau cov photosynthetic kho cov pa roj carbon dioxide hauv chloroplast.
Qhov thib ob, vim li cas Rubisco qeeb? qeeb thiab Steady Typical enzymes tuaj yeem ua tiav ib txhiab molecules persecond, tab sis rubisco kho tsuas yog txog peb carbon dioxide molecules ib ob. Cog hlwb them nyiaj rau qhov no qeeb nce los ntawm kev tsim cov enzyme ntau. Rubisco tom qab ntawd txuas cov pa oxygen mus rau cov khoom qab zib, tsim cov khoom tsis raug oxygenated.
Hauv qhov no, qhov teeb meem nrog Rubisco yog dab tsi?
Rubisco ntseeg tau tias yog cov protein ntau tshaj plaws hauv ntiaj teb. Txawm li cas los xij, Rubisco yog tsis muaj txiaj ntsig heev tuav CO 2, thiab nws muaj qhov phem dua teeb meem . Thaum lub concentration ntawm CO 2 nyob rau hauv cov huab cua sab hauv nplooj poob qis heev, Rubisco pib grabbingoxygen hloov.
Vim li cas Rubisco thiaj li muaj protein ntau?
Ribulose-1, 5-bisphosphate carboxylase / oxygenase ( Rubisco ) yog qhov tseem ceeb protein ntau inphotosynthesizing cog qhov chaw thiab cov protein ntau ntau nyob ntiaj teb. Kev sib sau ntawm carbohydrates kuj tseem tuaj yeem ua kom nrawm dua thiab Rubisco degradation nyob rau hauv tej yam kev mob.

Vim li cas qhov piv txwv tseem ceeb hauv kev lag luam zaub mov?
Kev kuaj cov zaub mov yog txheej txheem siv los xyuas tias cov khoom noj muaj kev nyab xeeb thiab tsis muaj cov kab mob phem, lossis nws tsuas muaj cov tshuaj ntxiv uas tau tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, los yog kom paub cov qib ntawm cov as-ham tam sim no
Vim li cas nws tseem ceeb kom paub tias koj txhais li cas ntxiv?
Txhais qhov seem. Kev txhais cov lus tseem ceeb yog qhov tseem ceeb thaum koj faib ua lej vim tias koj tuaj yeem tau txais qhov teeb meem tsis raug yog tias koj tsis txhais cov seem kom raug. Piv txwv li, nyob rau hauv ib lo lus teeb meem koj yuav tsum tau faib thiab faib tawm rau koj nrog ib tug seem thiab koj yuav tsum tau muab sau tseg
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
Yuav ua li cas yog vim li cas tus qauv ntawm ib qho enzyme tseem ceeb heev rau nws txoj haujlwm hauv cov khoom muaj sia?
Enzymes ua kom cov tshuaj tiv thaiv uas tshwm sim hauv cov hlwb. Qhov kev ua haujlwm no cuam tshuam ncaj qha rau lawv cov qauv, nrog rau txhua qhov enzyme tau tshwj xeeb zoo li tus ua kom muaj zog rau ib qho tshuaj tiv thaiv. Kev poob ntawm cov qauv ua rau poob haujlwm. - Kub, pH, thiab kev tswj cov molecules tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov enzymes
