Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv lub teeb thiab Calvin lub voj voog yog kev vam khom ntawm lub teeb hauv txhua hom tshuaj tiv thaiv hauv photosynthesis. Lub teeb pom kev hauv photosynthesis yog lub teeb-nyob ntawm qhov chaw Calvin lub voj voog (los yog cov tshuaj tiv thaiv tsaus nti hauv photosynthesis) yog lub teeb-yooj yim.
Photosynthesis yog hom khoom noj khoom haus autotrophic tshwm sim hauv cov nroj tsuag thiab lwm yam kab mob photosynthetic xws li algae thiab cyanobacteria. Nws yog txheej txheem anabolic ntawm kev tsim khoom noj. Photosynthesis nyob rau hauv cov nroj tsuag yuav siv sij hawm qhov chaw nyob rau hauv ob lub ntsiab txheej txheem. Lawv yog cov txheej txheem teeb pom kev zoo thiab lub voj voog Calvin. Lub teeb cov tshuaj tiv thaiv ntawm photosynthesis yog lub teeb-dependent txheej txheem uas converts hnub ci zog rau hauv tshuaj zog. Hauv qhov sib piv, Calvin lub voj voog tseem hu ua qhov tsaus ntuj cov tshuaj tiv thaiv ntawm photosynthesis yog txheej txheem lub teeb-yooj yim.
Lub Teeb Pom Kev yog dab tsi?
Teeb pom kev ntawm photosynthesis tshwm sim hauv cov thylakoid daim nyias nyias ntawm chloroplasts. Lawv yog cov tshuaj tiv thaiv lub teeb-dependent. Lawv hloov lub hnub ci zog rau lub zog tshuaj los ntawm kev ua ntawm chlorophyll. Muaj ob lub photosystems koom nrog hauv lub teeb pom kev. Namely, lawv yog photosystem kuv thiab photosystem II. Photosystems nqus lub teeb los ntawm lub hnub ci zog qhov chaw. Lawv nqus cov wavelength sib txawv hauv lub teeb. Tom qab ntawd, cov electrons hauv photosystems nqus lub zog no thiab tau txais kev zoo siab. Cov neeg txais hluav taws xob lees txais cov hluav taws xob hluav taws xob no.
Daim duab 01: Lub Teeb Teeb
Li no, dhau ntawm kev hloov ntawm electrons, phosphorylation tshwm sim los tsim adenosine tri phosphate (ATP). Txij li cov txheej txheem no yog nyob ntawm lub teeb, nws yog hu ua Photophosphorylation. Ntxiv rau qhov no, dej koom nrog hauv cov txheej txheem. Qhov no yog hu ua photolysis ntawm dej uas muab cov pa oxygen dawb thiab hydrogen ions. Lub hydrogen ion gradient yog qhov tseem ceeb hauv cov txheej txheem phosphorylation los tsim cov tshuaj electrochemical gradient. Lub teeb pom kev ntawm photosynthesis muaj ob pawg cyclic cov tshuaj tiv thaiv thiab tsis-cyclic cov tshuaj tiv thaiv.
Calvin Cycle yog dab tsi (Dark Reaction hauv Photosynthesis)?
Calvin lub voj voog kuj tseem hu ua qhov tsaus ntuj cov tshuaj tiv thaiv ntawm photosynthesis yog cov tshuaj tiv thaiv lub teeb. Lawv tshwm sim nyob rau hauv lub stroma ntawm chloroplast. Raws li, tsim cov suab thaj tebchaw nrog carbon-dioxide raws li qhov pib compound drives Calvin voj voog. Txawm li cas los xij, tsis muaj kev ua haujlwm ntawm electrons hauv Calvin voj voog. Cov pa roj carbon inorganic uas tshwm sim raws li carbon-dioxide kho hauv Calvin lub voj voog los tsim cov suab thaj triose. Lawv yog cov tshuaj tiv thaiv lub zog. Muaj peb theem tseem ceeb ntawm Calvin lub voj voog; lawv yog cov pa roj carbon fixation, txo, thiab rov tsim dua tshiab ntawm cov pa roj carbon compound pib.
Daim duab 02: Calvin Cycle
thawj carbon txais nyob rau hauv lub teeb-yooj yim kev xav yog 5 carbon qab zib hu ua Rubisco bisphosphate (RuBP). Rau cov pa roj carbon monoxide tsim yog li faib ua ob peb-carbon molecules hu ua Phosphoglyceric acid (PGA). PGA ces faib los tsim glyceraldehyde - 3 - phosphate thiab regenerates RuBP. Cov tsim glyceraldehyde - 3 - phosphate yog li siv los tsim cov piam thaj. Tsis tas li ntawd, muaj ob yam tseem ceeb ntawm kev tsaus ntuj. Lawv yog C3 txoj hauv kev uas tshwm sim hauv C3 nroj tsuag thiab C4 txoj hauv kev uas tshwm sim hauv C4 nroj tsuag.
Dab tsi yog qhov zoo sib xws ntawm Lub Teeb Pom Kev thiab Calvin Cycle?
- Ob txheej txheem tsim lub zog hauv daim ntawv ntawm ATP.
- Kuj, ob leeg yog enzyme-mediated.
- Tsis tas li ntawd, ob qho tib si tshwm sim hauv chloroplasts.
- Ntxiv mus, ob qho tib si txheej txheem tshwm sim hauv cov kab mob autotrophic.
Qhov txawv ntawm Lub Teeb Pom Kev thiab Calvin Cycle yog dab tsi?
Lub teeb pom kev hauv photosynthesis nyob ntawm lub teeb lub zog thaum Calvin lub voj voog (los yog cov tshuaj tiv thaiv tsaus nti hauv photosynthesis) tsis nyob ntawm lub teeb lub zog. Yog li ntawd, tis yog qhov sib txawv tseem ceeb ntawm lub teeb pom kev zoo thiab Calvin voj voog. Qhov sib txawv ntxiv ntawm lub teeb thiab Calvin lub voj voog yog tias lub teeb pom kev tshwm sim nyob rau hauv thylakoid membrane thaum Calvin voj voog tshwm sim hauv stroma ntawm chloroplast.
Ntxiv mus, muaj qhov sib txawv ntawm cov tshuaj tiv thaiv lub teeb thiab Calvin lub voj voog hauv cov khoom kawg. Qhov ntawd yog; Cov khoom kawg ntawm lub teeb pom kev yog ATP thiab NADPH thaum kawg cov khoom ntawm Calvin voj voog yog qabzib. Cov nram qab no infographic ntawm qhov sib txawv ntawm lub teeb pom kev zoo thiab Calvin lub voj voog muab ntau qhov sib txawv ntawm ob qho kev tawm tsam.
Summary – Teeb Reaction vs Calvin Cycle
Photosynthesis tshwm sim hauv cov kab mob photoautotrophic. Muaj ob hom photosynthesis raws li lawv dependence rau lub teeb xws li lub teeb-dependent cov tshuaj tiv thaiv thiab lub teeb-yooj yim tshwm sim. Raws li qhov tshwm sim, lub teeb-yeeb yaj kiab kuj hu ua Calvin cycle. Ntawm qhov tod tes, lub teeb-dependent tshwm sim los ntawm kev koom tes ntawm photosystems. Yog li, nws tshwm sim hauv thylakoid daim nyias nyias ntawm chloroplast. Nyob rau hauv sib piv, lub voj voog Calvin tshwm sim los ntawm kev tsim cov organic tebchaw. Yog li, qhov no tshwm sim hauv stroma ntawm chloroplast. Qhov no yog qhov txawv ntawm lub teeb pom kev zoo thiab Calvin lub voj voog.
