Ob theem ntawm photosynthesis: Photosynthesis yuav siv sij hawm qhov chaw nyob rau hauv ob theem: lub teeb-dependent tshwm sim thiab lub Calvin voj voog (lub teeb-yooj yim tshuaj tiv thaiv). Lub teeb-dependent kev tshwm sim, uas tshwm sim nyob rau hauv lub thylakoid membrane, siv lub teeb lub zog los ua ATP thiab NADPH.
Raws li txoj cai, 3 theem ntawm photosynthesis yog dab tsi?
Nws yog qhov yooj yim los faib cov photosynthetic txheej txheem hauv cov nroj tsuag ua plaub theem , txhua qhov tshwm sim nyob rau hauv ib cheeb tsam ntawm chloroplast: (1) nqus ntawm lub teeb, (2) electron thauj mus rau qhov txo ntawm NADP+ rau NADPH, ( 3 ) tiam ntawm ATP, thiab (4) kev hloov pauv ntawm CO2 nyob rau hauv carbohydrates (carbon fixation).
Ib tug kuj yuav nug, dab tsi theem ntawm photosynthesis yog o2 tsim? Photosynthesis tshwm sim hauv ob theem . Thaum thawj zaug theem , lub zog ntawm lub hnub ci yog absorbed los ntawm chloroplast. Dej siv tau, thiab oxygen yog ua thaum lub sij hawm no ib feem ntawm cov txheej txheem. Thaum lub sij hawm thib ob theem , carbon dioxide yog siv, thiab qabzib yog ua.
Kuj paub, dab tsi tshwm sim hauv theem 2 ntawm photosynthesis?
Theem ob: carbon fixation Qhov no theem kuj xav tau lub zog, uas yog muab los ntawm ATP ua los ntawm lub teeb pom kev zoo. ATP tau tawg los 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.
Dab tsi yog theem ntawm photosynthesis uas theem tshwm sim thawj zaug?
Cov theem ntawm photosynthesis yog lub teeb tshwm sim thiab lub voj voog Calvin. Lub teeb pom kev zoo tshwm sim ua ntej.
Pom zoo:
Lub npe ntawm cov tshuaj yog dab tsi uas lub zog khaws cia nyob rau hauv thawj theem ntawm photosynthesis?
Cov kev cuam tshuam ntawm lub teeb-dependent siv lub teeb lub zog los ua ob lub molecules uas xav tau rau theem tom ntej ntawm photosynthesis: lub zog cia molecule ATP thiab txo cov khoom siv hluav taws xob NADPH. Nyob rau hauv cov nroj tsuag, lub teeb tshwm sim tshwm sim nyob rau hauv lub thylakoid daim nyias nyias ntawm organelles hu ua chloroplasts
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
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
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
