Photosynthesis yog cov txheej txheem los ntawm cov nroj tsuag thiab lwm yam khoom ua zaub mov. Nws yog ib qho endothermic (coj hauv tshav kub) tshuaj txheej txheem uas siv lub hnub ci los hloov carbon dioxide rau hauv cov suab thaj uas lub cell siv tau los ua lub zog. Raws li cov nroj tsuag, ntau hom algae, protists thiab kab mob siv nws kom tau txais zaub mov.
Tsis tas li ntawd, dab tsi yog qhov txheej txheem ntawm photosynthesis?
Photosynthesis, cov txheej txheem uas cov nroj tsuag ntsuab thiab lwm yam kab mob hloov lub teeb lub zog rau hauv tshuaj zog. Thaum lub sij hawm photosynthesis nyob rau hauv cov nroj tsuag ntsuab, lub teeb lub zog yog ntes thiab siv los hloov dej , carbon dioxide, thiab minerals rau oxygen thiab lub zog-nplua nuj organic tebchaw.
Ib tug kuj yuav nug, vim li cas photosynthesis tseem ceeb heev? Cov nroj tsuag ntsuab thiab ntoo siv photosynthesis ua zaub mov los ntawm tshav ntuj, carbon dioxide thiab dej hauv qhov chaw: Nws yog lawv lub hauv paus ntawm lub zog. Cov qhov tseem ceeb ntawm photosynthesis nyob rau hauv peb lub neej yog cov pa oxygen nws tsim. Tsis muaj photosynthesis yuav muaj tsawg los tsis muaj oxygen nyob rau hauv lub ntiaj teb no.
Kuj nug, dab tsi yog txhais los ntawm cov txheej txheem photosynthesis?
npe. Cov txhais ntawm photosynthesis yog cov txheej txheem los ntawm cov nroj tsuag siv dej thiab carbon dioxide los tsim lawv cov zaub mov, loj hlob thiab tso pa ntau dhau rau hauv huab cua.
Ob txoj kev ntawm photosynthesis yog dab tsi?
Cov ob theem ntawm photosynthesis : Photosynthesis siv qhov chaw hauv ob theem: lub teeb-dependent tshwm sim thiab lub voj voog Calvin (lub teeb-yeeb yaj kiab tsis txaus ntseeg). Lub teeb-nyob ntawm cov tshuaj tiv thaiv, uas tshwm sim hauv thylakoid membrane, siv lub teeb lub zog los ua ATP thiab NADPH.

Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands
Vim li cas nws yog ib lub tswv yim zoo los cawm tag nrho cov txheej txheem ntawm koj cov extraction kom txog thaum kawg ntawm kev sim?
Kev ua yuam kev thaum lub sijhawm rho tawm (piv txwv li nqa nrog cov txheej txheem tsis raug), tuaj yeem daws tau yog tias cov kev daws tsis tau muab tso rau hauv lub thawv pov tseg! Cov khaubncaws sab nraud povtseg yuav tsum tau txais kev cawmdim kom txog thaum tom qab evaporation vim hais tias cov khoom xav tau yuav tsis soluble heev hauv cov kuab tshuaj siv
Cov xim dab tsi yog cov hlwb feem ntau ua ntej siv thawj cov xim rau cov txheej txheem Gram stain?
Ua ntej, siv lead ua violet, thawj stain, yog siv rau lub tshav kub-tso smear, muab tag nrho cov hlwb xim liab
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
