Nyob rau hauv photosynthesis, lub teeb-dependent tshwm sim coj qhov chaw ntawm thylakoid membranes. Sab hauv ntawm thylakoid membrane yog hu ua lub lumen, thiab sab nraum lub thylakoid membrane yog lub stroma, qhov twg lub teeb-yooj yim tshwm sim coj qhov chaw.
Ib yam li ntawd, Z txheej txheem ntawm kev thauj khoom hluav taws xob yog dab tsi?
Cov Z - Tswv yim Daim duab ntawm Photosynthesis. Rajni Govindjee: koj puas xav tau ntau tus thwjtim? Cov Electron Transport Txoj kev los ntawm Dej (H2O) rau NADP + (lub Nicotinamide Adenine Dinucleotide Phosphate, oxidized daim ntawv). Muaj ntau versions ntawm lub Z - tswv yim muaj nyob rau hauv cov ntaub ntawv.
Kuj Paub, Z Scheme Class 11 yog dab tsi? Lub electron thauj cov electrons ces tsiv downhill mus rau ib tug molecule ntawm lub zog-nplua nuj NADP+ thiab qhov sib ntxiv ntawm cov electrons no txo NADP+ rau NADPH + H+. Tag nrho tswv yim ntawm kev hloov ntawm electrons yog hu ua z - tswv yim , vim nws cov yam ntxwv zoo.
Ntxiv mus, Z lub tswv yim ntawm photosynthesis yog dab tsi?
Hauv Z - tswv yim , electrons raug tshem tawm los ntawm dej (sab laug) thiab tom qab ntawd muab tso rau hauv qis (tsis zoo siab) oxidized daim ntawv ntawm P680. Kev nqus ntawm photon excites P680 rau P680 *, uas "dhia" mus rau ib qho kev txo qis ntau hom. P680 * pub nws cov hluav taws xob rau quinone-cytochrome bf saw, nrog cov twj siv hluav taws xob.
Vim li cas tsis cyclic Photophosphorylation hu ua Z scheme?
Noncyclic Electron Flow. Daim duab 2. Lub Z scheme ntawm electron thauj mus rau ob lub photosystems. Qhov no yog schematic daim duab qhia kev ntws ntawm electrons los ntawm dej rau NADP +. Nws yog hu ua tus Z scheme vim nws txuas ob lub photosystems nyob rau hauv ib txoj kev uas zoo li tsab ntawv " Z ".

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Qhov twg yog qhov cua sov los ntawm qhov uas ua rau qhov tam sim no convection hauv lub mantle?
Lub tshav kub uas tsav cov convection tam sim no nyob rau hauv lub mantle los ntawm lub hauv paus ntawm lub ntiaj teb
