Ob tug kev yees duab nqus teeb lub zog los ntawm cov protein uas muaj cov xim, xws li chlorophyll. Cov teeb - nyob ntawm cov tshuaj tiv thaiv pib hauv kev yees duab II. Qhov no tshuaj tiv thaiv qhov chaw, hu ua P700, yog oxidized thiab xa cov hluav taws xob hluav taws xob siab kom txo tau NADP + rau NADPH.
Ntawm no, lub luag haujlwm ntawm photosystem 2 yog dab tsi?
Photosystem II yog thawj qhov txuas hauv cov saw hlau ntawm photosynthesis. Nws ntes photons thiab siv lub zog kom rho tawm electrons los ntawm dej molecules. Raws li cov electrons ntws los ntawm cov saw hlau, lawv tau siv los tso cov hydrogen ions hla daim nyias nyias, muab lub zog ntau dua rau ATP synthesis.
Ib yam li ntawd, lub luag haujlwm ntawm photosystem 1 thiab 2 yog dab tsi? Qhov tseem ceeb muaj nuj nqi ntawm kev yees duab Kuv nyob hauv NADPH synthesis, qhov twg nws tau txais cov electrons los ntawm PS II . Qhov tseem ceeb muaj nuj nqi ntawm photosystem II yog nyob rau hauv hydrolysis ntawm dej thiab ATP synthesis. PSI yog tsim los ntawm ob lub subunits uas yog psaA thiab psaB.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub luag hauj lwm ntawm photosystem 1 nyob rau hauv lub teeb tshwm sim?
Photosystem Kuv thiab II thiab cov Teeb pom kev zoo Lub hom phiaj ntawm cov tshuab yees duab no yog txhawm rau sau lub zog dhau ntawm "nthuav" ntau ntawm wavelengths thiab mloog zoo rau ib molecule npe a tshuaj tiv thaiv center uas siv lub zog kom dhau ib ntawm nws cov electrons mus rau ib tug series ntawm enzymes.
Lub luag haujlwm ntawm p680+ nyob rau hauv lub teeb pom kev yog dab tsi?
Qhov tshwm sim zoo them P680+ yog qhov muaj zog tshaj plaws paub txog lom oxidant (electron acceptor). Lub luag haujlwm ntawm P680+ yog dab tsi hauv cov teeb pom kev zoo ? Hauv Photosystem II (PS II), teeb lub zog yog siv los tsim cov khoom siv hluav taws xob uas muaj zog txaus rau oxidize dej.

Lub luag haujlwm ntawm CDK yog dab tsi hauv lub cev ua haujlwm ntawm tes tshwj xeeb hauv lub voj voog ntawm tes?
Los ntawm phosphorylation, Cdks teeb liab lub xov tooj ntawm tes uas nws tau npaj kom dhau mus rau theem tom ntej ntawm lub voj voog ntawm tes. Raws li lawv lub npe qhia, Cyclin-Dependent Protein Kinases yog nyob ntawm cyclins, lwm chav kawm ntawm kev tswj hwm cov protein. Cyclins khi rau Cdks, ua kom cov Cdks rau phosphorylate lwm cov molecules
Dab tsi yog qhov txawv ntawm lub teeb pom kev thiab pom tsis pom?
Tsis muaj qhov sib txawv ntawm lub teeb pom kev thiab pom tsis pom lub teeb xws li xov tooj cua nthwv dej thiab X rays. Lawv yog tag nrho cov electromagnetic tsis txawv nyob rau hauv ib txoj kev xwb: lawv wavelength. Lub teeb ultraviolet, X rays, thiab gamma rays tag nrho muaj luv luv wavelengths tshaj li pom lub teeb
Dab tsi yog cov haujlwm ntawm photosystem I thiab photosystem II hauv cov nroj tsuag?
Photosystem I thiab photosystem II yog ob qho tib si ntau cov protein ntau uas muaj cov pigments tsim nyog los sau cov photons thiab siv lub teeb lub zog los catalyze thawj photosynthetic endergonic cov tshuaj tiv thaiv uas ua rau muaj zog sib txuas
Lub luag haujlwm ntawm carbon nyob rau hauv molecular ntau haiv neeg ntawm lub neej yog dab tsi?
Cov pa roj carbon monoxide yog qhov tsis sib xws hauv nws lub peev xwm los tsim cov loj, complex, thiab ntau hom molecules. Cov proteins, DNA, carbohydrates, thiab lwm yam molecules uas paub qhov txawv ntawm cov khoom muaj sia los ntawm cov khoom siv tsis muaj sia yog txhua tus muaj cov pa roj carbon atoms sib txuas rau ib leeg thiab rau cov atoms ntawm lwm cov khoom
Lub luag haujlwm tseem ceeb ntawm lub teeb pom kev ntawm photosynthesis yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
