Thaum photosynthesis raug tso tseg tom qab ob vib nas this, cov khoom siv hluav taws xob tseem ceeb yog PGA, yog li ntawd tau txheeb xyuas tias yog thawj qhov chaw ruaj khov tsim thaum lub sijhawm carbon dioxide fixation nyob rau hauv ntsuab nroj tsuag. PGA yog peb-carbon compound, thiab hom ntawm photosynthesis yog li hu ua C3.
Ib yam li ntawd, thawj cov khoom ntawm carbon fixation yog dab tsi?
"C4" hais txog plaub- carbon molecule uas yog thawj cov khoom ntawm hom no carbon fixation.
Kuj Paub, cov khoom ntawm carbon fixation yog dab tsi? Hauv cov pa roj carbon fixation theem, carbon dioxide Nws txuas nrog RuBP los ntawm enzyme rubisco. Qhov tshwm sim 6-carbon cov khoom sai sai faib ua ob lub molecules ntawm peb-carbon compound (3-phosphoglycerate). Thaum peb carbon dioxide molecules nkag mus rau hauv lub voj voog, rau molecules ntawm 3-phosphoglycerate yog tsim.
Ntxiv mus, dab tsi yog thawj qhov khoom ruaj khov ntawm Calvin voj voog?
phosphoglyceric acid
Dab tsi yog carbon assimilation hauv cov nroj tsuag?
Cov pa roj carbon fixation los yog sarbon assimilation yog cov txheej txheem hloov dua siab tshiab ntawm inorganic carbon ( carbon dioxide) rau cov organic tebchaw los ntawm cov kab mob nyob. Cov piv txwv tseem ceeb tshaj plaws yog photosynthesis, txawm tias chemosynthesis yog lwm hom carbon fixation uas tuaj yeem tshwm sim thaum tsis muaj hnub ci.

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 pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Cov khoom lag luam ruaj khov yog dab tsi?
Cov khoom lag luam mus tas li hais txog cov khoom tiag lossis cov khoom tsim los yog cov txiaj ntsig uas tshwm sim los ntawm tus cwj pwm thiab siv los ntawm cov kws qhia ntawv tsis tu ncua hauv ntau txoj hauv kev. Qhov txiaj ntsig ntawm cov khoom lag luam mus tas li yuav yog suav cov ntawv uas nyob hauv lub rooj tom qab tus tub ntxhais kawm tau ua tiav tu
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Nws hu li cas thaum cov khoom nyob hauv qhov chaw ruaj khov thiab vibrate ntawm qhov chaw?
Daim duab 2.1 Cov khoom nyob rau hauv cov khoom yog tsau rau lawv cov neeg nyob ze. Lawv vibrate ib ncig ntawm lawv txoj hauj lwm ruaj. Aerosols vam khom rau cov khoom khib nyiab, kua thiab roj thiab lawv coj li cas. Txoj kev xav uas piav txog qhov no yog Kinetic Theory of Matter
