Ribulose-1, 5-bisphosphate carboxylase/oxygenase, feem ntau paub los ntawm cov ntawv luv Rubisco , rubisco , RuBPCase, los yog RuBPco, yog ib qho enzyme koom nrog hauv thawj kauj ruam tseem ceeb ntawm kev kho cov pa roj carbon monoxide, txheej txheem uas cov pa roj carbon dioxide hloov pauv los ntawm cov nroj tsuag thiab lwm cov kab mob photosynthetic muaj zog nplua nuj.
Ib yam li ntawd, koj tuaj yeem nug, puas yog RuBisCO thiab RuBP tib yam?
RUB ces yog 5-carbon intermediate koom nrog Calvin voj voog. RUB yog lub substrate uas lub enzyme Rubisco siv los kho cov pa roj carbon dioxide thiab thaum kawg tsim ob lub molecules ntawm glyceraldyde-3-phosphat RubBisCO , yog anenzyme koom nrog Calvin Cycle uas catalyzes ib qho tseem ceeb hauv kev txhim kho carbon.
Ib yam li ntawd, tus qauv ntawm RuBisCO yog dab tsi? RubBisCO Kuv yog ua los ntawm ntau cov protein molecules, los yog subunits. Tshwj xeeb tshaj yog, nws muaj yim loj thiab yim subunits me me. Enzymes zoo li RubBisCO muaj activesites, los yog qhov chaw uas substrates khi. Lub substrate yog txhua yam theenzyme ua rau (peb yuav tau mus RubBisCO substratesshortly).
Ib yam li ntawd, hom enzyme twg yog RuBisCO?
Cov enzyme ribulose-1, 5-bisphosphatecarboxylase/oxygenase, feem ntau paub los ntawm lub npe luv RubBisCO los yog xwb rubisco yog siv nyob rau hauv Calvin cycleto catalyze thawj kauj ruam tseem ceeb ntawm carbon fixation.
RuBisCO Activase yog dab tsi?
Kev kho cua sov ntawm cov nplooj spinach tsis zoo tau pom tias ua rau muaj kev sib koom ua ke ntawm thylakoid membrane ntawm kwv yees li 40 kDa stromal protein. Cov protein no tau txheeb xyuas tias rubiscoactivase . Fractionation ntawm thylakoid daim nyias nyias tau qhia txog kev sib koom ua ke ntawm rubisco activase nrog thylakoid-bound polysomes.

Lub ntsiab lus ntawm dav hlau geometry yog dab tsi?
Hauv kev ua lej, lub dav hlau yog lub tiaj tus, ob sab ntawm qhov chaw uas txuas mus tsis kawg. Lub dav hlau yog ob-dimensional analogue ntawm ib qho point (zero dimensions), ib kab (ib dimension) thiab peb-dimensional qhov chaw
Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
Dab tsi yog qhov kev teeb tsa hluav taws xob dav dav ntawm SPD thiab F thaiv cov ntsiab lus?
Sau cov txheej txheem hluav taws xob sab nraud ntawm s-, p-, d- thiab f-block ntsiab. Element General sab nrauv hluav taws xob configuration p–block(metals & non metals) ns2np1–6, where n = 2 – 6 d–block(transition elements) (n–1) d1–10 ns0–2, where n = 4 – 7 f -block(internal transition elements) (n–2)f1–14(n–1)d0–10ns2, where n=6–7
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Dab tsi yog cov lej thiab cov lej rational Yuav ua li cas cov ntsiab lus kos rau ntawm lub dav hlau sib koom tes?
Raws li peb tau hais, cov ntsiab lus ntawm lub dav hlau sib koom ua ke yog sawv cev raws li (a, b), qhov twg a thiab b yog tus lej lej. Rational cov lej yog cov lej uas tuaj yeem sau ua feem, p / q, qhov p thiab q yog tus lej. Peb hu rau x-coordinate ntawm lub point thiab peb hu b tus y-coordinate ntawm lub point
