Qhov sib txawv ntawm Teeb thiab Tsaus Teeb
| Teeb pom kev zoo | Tsaus Reaction |
|---|---|
| Cov khoom kawg yog ATP thiab NADPH. | Glucose yog qhov khoom kawg. ATP thiab NADPH pab tsim cov piam thaj. |
| Cov dej molecules faib ua hydrogen thiab oxygen. | Glucose yog tsim. Co2 yog siv rau hauv qhov tsaus ntuj. |
Tsuas yog li ntawd, cov khoom ntawm cov tshuaj tiv thaiv tsaus nti yog dab tsi?
Cov tshuaj tiv thaiv tsaus nti tshwm sim sab nraud ntawm thylakoids. Nyob rau hauv no cov tshuaj tiv thaiv, lub zog los ntawm ATP thiab NADPH yog siv los kho carbon dioxide ( CO2 ). Cov khoom ntawm cov tshuaj tiv thaiv no yog cov piam thaj molecules thiab lwm cov organic molecules tsim nyog rau kev ua haujlwm ntawm tes thiab cov metabolism.
Ib tug kuj yuav nug, dab tsi yog lub teeb thiab tsaus nti? Teeb pom kev zoo xav tau teeb los tsim cov organic zog molecules (ATP thiab NADPH). Lawv tau pib los ntawm cov xim xim, feem ntau yog xim ntsuab chlorophylls. Tsaus tshuaj tiv thaiv siv cov organic zog molecules (ATP thiab NADPH). Qhov no tshuaj tiv thaiv Lub voj voog tseem hu ua Calvin Benison Cycle, thiab nws tshwm sim hauv stroma.
Ib yam li ntawd, nws tau nug, dab tsi yog cov khoom kawg ntawm lub teeb thiab tsaus nti?
Muaj ob cov khoom kawg ntawm teeb pom kev zoo ntawm photosynthesis, ATP thiab NADPH. Cov molecules no yog tsim thaum lub sij hawm cyclic thiab tsis-cyclic photophosphorylation cov tshuaj tiv thaiv . Cov no yog cov cov khoom uas yog siv nyob rau hauv lub tsaus nti.
Cov khoom ntawm lub teeb theem yog dab tsi?
Hauv lub voj voog no ATP thiab NADPH, tsim nyob rau hauv lub teeb theem, muab lub zog thiab electrons hloov carbon dioxide (CO2) rau carbohydrates (C H O) molecules. Txawm hais tias theem no yog hu ua theem tsaus ntuj nws tshwm sim nyob rau hauv lub teeb thiab kuj nyob rau hauv qhov tsaus ntuj raws li ntev raws li cov khoom ntawm lub teeb theem tseem muaj.

Dab tsi yog qhov me me ntawm cov khoom uas khaws cov khoom ntawm lub caij?
Ib qho atom yog qhov tsawg tshaj plaws ntawm txhua lub caij uas tseem khaws cov yam ntxwv ntawm lub caij ntawd. Ib daim ntawm ib lub caij uas peb tuaj yeem pom lossis kov yog ua los ntawm ntau, ntau atoms thiab tag nrho cov atoms yog tib yam lawv txhua tus muaj tib tus naj npawb ntawm protons
Dab tsi yog cov reactants thiab cov khoom ntawm lub teeb pom kev zoo?
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. RuBP thiab oxygen yog cov khoom lag luam
Dab tsi yog qhov zoo sib xws ntawm cov khoom thiab cov khoom sib txuas?
Cov ntsiab lus thiab cov tebchaw yog cov tshuaj homogeneous nkaus xwb thiab lawv muaj qhov sib xyaw tas li thoob plaws. Cov ntsiab lus thiab cov tebchaw tsis tuaj yeem sib cais rau hauv lawv cov khoom sib xws los ntawm kev siv lub cev. Cov tshuaj thiab cov khoom sib tov yog tsim los ntawm cov khoom sib txawv lossis cov atom sib txawv
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)
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
