Nroj tsuag ua pa txhua lub sijhawm, hnub thiab hmo . Tab sis photosynthesis nkaus xwb tshwm sim thaum nruab hnub thaum muaj hnub ci. Nyob ntawm seb lub hnub ci ntau npaum li cas, cov nroj tsuag ua tau muab tawm los yog muab tso rau hauv oxygen thiab carbon dioxide raws li hauv qab no?1?. Tsaus - Tsuas yog ua pa xwb.
Yog li ntawd, puas photosynthesis tshwm sim thaum hmo ntuj?
Yog lawm, photosynthesis YOG tshwm sim thaum hmo ntuj . Photosynthesis yog cov txheej txheem uas phytoplankton siv lub hnub ci los hloov cov pa roj carbon dioxide rau hauv cov zaub mov thiab tso tawm oxygen raws li cov khoom lag luam. Photosynthesis yog tsav los ntawm tshav ntuj.
Vim li cas photosynthesis tsis tshwm sim thaum hmo ntuj? Photosynthesis ua tsis tau coj qhov chaw thaum hmo ntuj Cov txheej txheem no yuav tsum muaj hnub ci, huab cua thiab dej. Ntawm hmo muaj tsis muaj hnub ci.
Tib neeg kuj nug, qhov twg theem ntawm photosynthesis tuaj yeem ua haujlwm hauv qhov tsaus ntuj?
LUB SIJ HAWM TAM SIM NO (Lub CALVIN CYCLE) Txawm hais tias theem no hu ua qhov tsaus ntuj nws tshwm sim hauv lub teeb thiab tseem nyob hauv qhov tsaus ntuj ntev li ntev tau cov khoom ntawm lub teeb theem tseem muaj. Cov theem tsaus ua haujlwm yog ATP , NADPH thiab carbon dioxide tam sim no.
Yuav ua li cas rau cov nroj tsuag thaum hmo ntuj?
Nroj tsuag Ua lej kom ciaj sia Hmo ntuj . Thaum lub hnub ci ntsa iab, nroj tsuag ua photosynthesis. Hauv qhov txheej txheem no, lub nroj tsuag hloov tshav ntuj, dej thiab carbon dioxide mus rau hauv lub zog khaws cia nyob rau hauv daim ntawv ntawm ntev chains ntawm qab zib, hu ua starch. Ntawm hmo , cov nroj tsuag hlawv cov hmoov txhuv nplej siab no kom roj txuas ntxiv mus.

Dab tsi yog qhov laj thawj tseem ceeb uas koj tuaj yeem hnov lub suab nrov nyob deb ntawm dej thaum hmo ntuj?
Qhov kub thiab txias inversion yog vim li cas vim li cas lub suab tuaj yeem hnov ntau dua qhov kev ncua deb ntawm hmo ntuj tshaj li thaum nruab hnub - ib qho cuam tshuam feem ntau tsis raug rau kev puas siab puas ntsws tshwm sim thaum hmo ntuj nyob ntsiag to
Dab tsi tshwm sim ntawm Theodor Engelmann qhov kev sim nto moo qhia rau nws uas wavelength S yog tus tsav tsheb zoo tshaj plaws ntawm photosynthesis?
Cov kab mob sib sau ua ke ntau tshaj plaws nyob ze ntawm ib feem ntawm cov alga uas tau nthuav tawm cov xim liab thiab xiav wavelengths. Engelmann qhov kev sim ua kom pom tias lub teeb liab thiab xiav yog lub zog zoo tshaj plaws rau photosynthesis
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 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
