Qhov thib ob theem ntawm photosynthesis muaj xws li carbonfixation thiab hu ua qhov tsaus ntuj tshuaj, los yog Calvin cycle. Photosynthesis pib nrog thawj theem, hu ua lightreactions. Ntawm no, lub zog yog lub hnub ci yog sau thiab hloov mus rau hauv tshuaj zog hauv daim ntawv ntawm NADPH thiab ATP.
Khaws qhov no hauv kev xav, dab tsi yog theem ob ntawm photosynthesis hu ua?
Daim duab: Ob theem ntawm photosynthesis : Photosynthesis tshwm sim nyob rau hauv ob theem :light-dependent reactions and the Calvin cycle (light-independentreactions). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv cov thylakoid membrane, siv lub teeb lub zog los ua ATP thiab NADPH.
Ib sab saum toj no, qhov twg yog theem ob ntawm photosynthesis tshwm sim? Cov theem ob ntawm photosynthesis siv qhov chaw Nyob rau hauv lub stroma nyob ib ncig ntawm lub thylakoid daim nyias nyias ntawm chloroplast. Cov tshuaj tiv thaiv ntawm no theem ua tau tshwm sim tsis muaj lub teeb, yog li lawv qee zaum hu ua lub teeb-yooj yim lossis tsaus ntuj.
Kuj paub, 2 hom photosynthesis yog dab tsi?
Muaj ob hom photosynthetic txheej txheem: oxygen photosynthesis thiab anoxygenic photosynthesis . Cov ntsiab cai dav dav ntawm anoxygenic thiaboxygenic photosynthesis zoo sib xws, tab sis oxygenic photosynthesis Nws yog feem ntau pom nyob rau hauv cov nroj tsuag, algae thiab cyanobacteria.
Dab tsi yog qhov ua haujlwm ntawm ATP hauv Theem 2 ntawm photosynthesis?
Theem ob: carbon fixation Qhov no theem kuj xav tau lub zog, uas yog muab los ntawm lub ATP ua los ntawm lub teeb pom kev zoo. Cov ATP yog tawg kom tso tawm lub zog uas yog siv los ua ke hydrogen (los ntawm lub teeb pom kev zoo) nrog carbon dioxide los tsim cov suab thaj.
Pom zoo:
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Ob theem tseem ceeb ntawm photosynthesis yog dab tsi thiab txhua theem tshwm sim nyob qhov twg?
Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent kev tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim kev xav). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid daim nyias nyias, siv lub teeb lub zog los ua ATP thiab NADPH
Dab tsi yog qhov voltage ntawm ob theem hauv 3 theem khoom?
Voltage ntawm ob theem hu ua Kab voltage. Kab voltage = 1.73 * Phase voltage. Hluav taws xob hluav taws xob nruab nrab ntawm ib theem 'nyob' thiab 'tsis nruab nrab' hauv peb theem kev faib tawm yog 220 V
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
