Photosynthesis , cov txheej txheem uas cov nroj tsuag ntsuab thiab lwm yam kab mob hloov lub teeb lub zog mus rau hauv tshuaj zog. Thaum photosynthesis Nyob rau hauv cov nroj tsuag ntsuab, lub teeb lub zog yog ntes thiab siv los hloov dej, carbon dioxide, thiab minerals rau hauv oxygen thiab lub zog-nplua nuj organic tebchaw.
Thiab cov lus nug yog, ua li cas photosynthesis ua haujlwm ib kauj ruam?
Photosynthesis yog multi- kauj ruam txheej txheem uas yuav tsum tau tshav ntuj, carbon dioxide, thiab dej ua substrates. Nws tsim cov pa oxygen thiab glyceraldehyde-3-phosphate (G3P lossis GA3P), yooj yim carbohydrate molecules uas muaj zog thiab tuaj yeem hloov mus rau hauv qabzib, sucrose, lossis lwm yam qab zib molecules.
Kuj Paub, Dab tsi yog photosynthesis piav qhia nws cov txheej txheem? Piav: Lub tshuab ntawm photosynthesis yog oxidation - txo cov tshuaj tiv thaiv. Nyob rau hauv cov txheej txheem no lub teeb lub zog yog daig los ntawm chloroplasts thiab atmospheric carbon dioxide yog tsau raws li cov pa roj carbon monoxide thiab undergo ntau lub voj voog hu ua curbs cycle thiab tsim cov suab thaj raws li cov khoom kawg nrog rau evolution ntawm oxygen.
Ua kom pom qhov no, chlorophyll ua haujlwm li cas hauv photosynthesis?
Chlorophyll yog qhov tseem ceeb rau photosynthesis , uas tso cai rau cov nroj tsuag kom nqus tau lub zog ntawm lub teeb. Chlorophyll molecules yog teem nyob rau hauv thiab ib ncig ntawm lub photosystems uas yog embedded nyob rau hauv lub thylakoid daim nyias nyias ntawm chloroplasts. Cov khub no cuam tshuam qhov kawg ua haujlwm ntawm chlorophylls , them nyiaj sib cais, ua rau biosynthesis.
Thawj kauj ruam ntawm photosynthesis yog dab tsi?
Cov thawj theem ntawm photosynthesis yog lub teeb nyob ntawm cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no tshwm sim ntawm thylakoid membrane hauv chloroplast. Lub sijhawm no theem Lub teeb lub zog hloov mus rau ATP (tshwj xeeb zog) thiab NADPH (txo lub zog).

Yuav ua li cas feem ntau yuav tshwm sim yog tias cov ribosomes hauv lub cell tsis ua haujlwm?
Ribosomes yog organelles uas tsim cov proteins. Cells siv cov protein los ua cov haujlwm tseem ceeb xws li kho cov cellular puas thiab coj cov txheej txheem tshuaj. Yog tias tsis muaj cov ribosomes no, cov hlwb yuav tsis tuaj yeem tsim cov protein thiab yuav tsis tuaj yeem ua haujlwm zoo
Yuav ua li cas photosynthesis ua haujlwm yooj yim?
Photosynthesis yog cov txheej txheem uas cov nroj tsuag thiab lwm yam ua zaub mov. Nws yog ib qho endothermic (siv cua sov) cov txheej txheem tshuaj uas siv lub hnub ci tig carbon dioxide rau hauv cov suab thaj uas lub xov tooj ntawm tes siv tau los ua lub zog. Raws li cov nroj tsuag, ntau hom algae, protists thiab kab mob siv nws kom tau zaub mov
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
Lub colorimeter ua haujlwm li cas qib biology?
Lub colorimeter yog ib qho cuab yeej uas sib piv cov nqi ntawm lub teeb uas tau txais los ntawm kev daws teeb meem nrog tus nqi uas tuaj yeem tau txais los ntawm cov qauv ntawm cov kuab tshuaj ntshiab. Cov tshuaj nqus lub teeb rau ntau yam laj thawj. Pigments nqus lub teeb ntawm qhov sib txawv wavelength
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
