Photosynthesis hauv cov nroj tsuag ua tau tau piav nyob rau hauv plaub theem , qho tshwm sim hauv qee qhov chaw ntawm chloroplast. Hauv theem 1 , lub teeb yog absorbed los ntawm chlorophyll ib tug molecules khi rau cov tshuaj tiv thaiv-center proteins nyob rau hauv lub thylakoid membrane.
Hauv qhov no, yuav ua li cas hauv Theem 1 ntawm photosynthesis?
Theem ib ntawm photosynthesis yog lub teeb-dependent cov tshuaj tiv thaiv, nyob rau hauv lub cev siv lub hnub ci los ua cov cab kuj molecules rau lub zog. Lub sijhawm no theem , hnub ci cuam tshuam nrog chlorophyll, zoo siab rau nws cov electrons mus rau lub zog siab dua.
Tom qab ntawd, lo lus nug yog, qhov twg 2 theem ntawm photosynthesis tshwm sim? Lub teeb-dependent cov tshuaj tiv thaiv coj qhov chaw nyob rau hauv thylakoid daim nyias nyias nyob rau hauv lub granum (pawg ntawm thylakoids), nyob rau hauv lub chloroplast. Ob tug theem ntawm photosynthesis : Photosynthesis tshwm sim nyob rau hauv ob theem : Lub teeb-nyob ntawm cov tshuaj tiv thaiv thiab Calvin lub voj voog (lub teeb-yeeb yaj kiab).
Ntawm no, qhov twg theem ib ntawm photosynthesis tshwm sim?
Theem Ib : Lub teeb Reactions Nyob rau hauv lub teeb-dependent txheej txheem, uas yuav siv sij hawm qhov chaw nyob rau hauv grana, lub stacked membrane qauv nyob rau hauv chloroplasts, lub zog ncaj qha ntawm lub teeb pab cov nroj tsuag ua molecules uas nqa lub zog rau kev siv nyob rau hauv qhov tsaus ntuj nti. theem ntawm photosynthesis.
Dab tsi yog thawj feem ntawm photosynthesis?
Cov txheej txheem ntawm photosynthesis muab faib ua ob qhov tseem ceeb. Thawj ntu yog hu ua lub teeb nyob ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no tshwm sim thaum lub teeb lub zog raug ntes thiab thawb mus rau hauv cov tshuaj hu ua ATP . Qhov thib ob ntawm cov txheej txheem tshwm sim thaum lub ATP yog siv los ua cov piam thaj (Calvin Cycle).
Pom zoo:
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
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
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
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
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
