Photosystem Kuv (PSI, lossis plastocyanin-ferredoxin oxidoreductase) yog qhov thib ob kev yees duab nyob rau hauv photosynthetic teeb pom kev zoo ntawm algae, nroj tsuag, thiab ib co kab mob. Photosystem Kuv yog ib qho membrane protein complex uas siv lub teeb lub zog rau tsim tawm lub siab muaj zog nqa ATP thiab NADPH.
Dhau li ntawd, dab tsi yog tsim nyob rau hauv photosystem 2?
Photosystem II yog thawj membrane protein complex nyob rau hauv oxygenic photosynthetic kab mob nyob rau hauv cov xwm. Nws tsim tawm atmospheric oxygen rau catalyze cov duab-oxidation ntawm dej los ntawm kev siv lub teeb lub zog. Nws oxidizes ob molecules ntawm dej rau hauv ib lub molecule ntawm molecular oxygen.
Ib sab saum toj no, dab tsi tshwm sim hauv photosystem 1? Qhov xwm txheej uas tshwm sim hauv photosystem kuv yog tias electrons raug xa mus rau ferredoxin. Qhov no yog ib feem ntawm photosynthetic Lub teeb tshwm sim uas ua rau siv lub teeb lub zog hloov hluav taws xob los ntawm plastocyanin rau ferredoxin.
Tom qab ntawd, lub hom phiaj ntawm photosystem 1 thiab 2 yog dab tsi?
Photosystem Kuv thiab II thiab Lub Teeb Pom Kev The lub hom phiaj ntawm cov duab tshuab no yog los sau lub zog dhau ntawm "ntev" ntau ntawm wavelengths thiab mloog zoo rau ib qho molecule hu ua lub chaw tshuaj tiv thaiv uas siv lub zog kom dhau ib qho ntawm nws cov electrons mus rau cov enzymes series.
Puas yog ATP yog cov khoom ntawm photosystem 1?
Electrons los ntawm dej molecules hloov cov uas poob los ntawm kev yees duab II. False-NADPH 4. ATP yog cov cov khoom ntawm photosystem Kuv. ATP thiab NADPH yog ob hom neeg nqa khoom protein.
Pom zoo:
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 photosystem 2 nyob rau hauv lub teeb pom kev yog dab tsi?
Ob lub photosystems nqus lub teeb lub zog los ntawm cov proteins uas muaj cov xim, xws li chlorophyll. Lub teeb-dependent tshwm sim pib hauv photosystem II. Qhov chaw tshuaj tiv thaiv no, hu ua P700, yog oxidized thiab xa cov hluav taws xob hluav taws xob siab kom txo tau NADP + rau NADPH
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Dab tsi yog cov ions nyob rau hauv siab tshaj plaws concentration nyob rau hauv lub extracellular kua?
Cov tshuaj no nyob rau hauv cov kua dej extracellular thiab intracellular. Nyob rau hauv cov kua dej extracellular, cov cation loj yog sodium thiab cov anion loj yog chloride. Qhov loj cation nyob rau hauv cov kua dej intracellular yog poov tshuaj. Cov electrolytes no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm homeostasis
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
