Teeb lub zog yog hloov mus rau chemical zog thaum lub sij hawm thawj theem ntawm photosynthesis, uas muaj ib tug series ntawm tshuaj cov tshuaj tiv thaiv hu ua lub teeb - raws li kev xav . Cov nroj tsuag ua ib daim ntawv ntawm photosynthesis hu ua oxygenic photosynthesis.
Yog li ntawd, dab tsi yog lub teeb nyob rau hauv cov tshuaj lom neeg biology?
Teeb - nyob ntawm cov tshuaj tiv thaiv . Los ntawm Biology -Cov phau ntawv txhais lus online | Biology - Cov phau ntawv txhais lus online. Txhais. Lub series ntawm biochemical cov tshuaj tiv thaiv nyob rau hauv photosynthesis uas yuav tsum tau teeb lub zog uas raug ntes los ntawm teeb -absorbing pigments (xws li chlorophyll) kom hloov mus rau hauv tshuaj zog hauv daim ntawv ntawm ATP thiab NADPH.
Kuj Paub, qhov teeb meem nyob qhov twg tshwm sim? Nyob rau hauv photosynthesis, lub teeb - kev cuam tshuam tshwm sim tshwm sim ntawm thylakoid daim nyias nyias. Sab hauv ntawm lub thylakoid membrane yog hu ua lub lumen, thiab sab nraum lub thylakoid membrane yog lub stroma, qhov twg teeb - ywj siab kev tshwm sim tshwm sim.
Kuj Paub, vim li cas lub teeb nyob ntawm qhov kev xav hu ua li ntawd?
siv lub zog los ntawm lub hnub ci los tsim cov pa roj carbon dioxide thiab hloov ADP thiab NADP + rau hauv cov khoom siv hluav taws xob ATP thiab NADPH. Piav vim li cas cov teeb - raws li kev xav yog npe as : Qhov no txhais tau tias koj yuav tsum muaj lub teeb ntawm. Lub hauv paus ntawm cov pa oxygen yog dej.
Lub teeb nyob ntawm qhov kev xav ua li cas tsim ATP?
Hauv teeb - raws li kev xav , lub zog nqus los ntawm lub hnub ci yog khaws cia los ntawm ob hom hluav taws xob-carrier molecules: ATP thiab NADPH. Lub zog tsim tawm los ntawm cov dej hydrogen ion tso cai ATP synthase mus txuas ib tug thib peb phosphate rau ADP, uas tsim ib tug molecule ntawm ATP hauv cov txheej txheem hu ua photophosphorylation.

Lub teeb sib tham txog tej yam ntuj tso thiab manmade qhov chaw ntawm lub teeb yog dab tsi?
Tej qhov chaw ntawm lub teeb muaj xws li lub hnub, hnub qub, hluav taws, thiab hluav taws xob nyob rau hauv cua daj cua dub. Tseem muaj qee cov tsiaj thiab nroj tsuag uas tuaj yeem tsim lawv tus kheej lub teeb, xws li fireflies, jellyfish, thiab nceb. Qhov no hu ua bioluminescence. Artificial light yog tsim los ntawm tib neeg
Dab tsi yog qhov txawv ntawm wavelength ntawm lub teeb liab thiab lub teeb violet?
Violet lub teeb yog hluav taws xob hluav taws xob hluav taws xob nrog wavelengths ntawm 410 nanometers thiab lub teeb liab muaj awavelength ntawm 680 nanometers. Qhov ntau ntawm wavelengths (400 - 700 nm) ntawm lub teeb pom kev yog nyob nruab nrab ntawm lub electromagnetic spectrum (Fig.1)
Qhov txawv ntawm lub teeb dawb thiab lub teeb dub yog dab tsi?
Dub tsuas yog qhov tsis muaj lub teeb, vim tias nws tsis nyob los yog vim nws tau nqus thiab tsis pom. Yog li hu ua 'dub teeb' tsuas yog ultra-violetlight, uas yog lub teeb zoo tib yam (electromagneticradiation) uas yog siab tshaj qhov pom spectrum. Lub teeb twg hu ua lub teeb dawb?
Dab tsi yog cov reactants ntawm lub teeb Dependent cov tshuaj tiv thaiv?
Hauv photosynthesis, chlorophyll, dej, thiab carbon dioxide yog reactants. GA3P thiab oxygen yog cov khoom lag luam. Hauv photosynthesis, dej, carbon dioxide, ATP, thiab NADPH yog reactants
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
