Photosynthesis yog cov txheej txheem los ntawm cov kab mob uas muaj cov xim chlorophyll hloov lub teeb lub zog rau hauv cov khoom siv hluav taws xob uas tuaj yeem khaws cia rau hauv cov ntawv cog lus ntawm cov organic molecules (piv txwv li, suab thaj).
Ib yam li ntawd, cov kab mob photosynthetic hloov lub hnub lub zog rau hauv cov tshuaj lom neeg li cas?
Photosynthesis . Daim duab 2.3: Photosynthesis : Nyob rau hauv tus txheej txheem ntawm photosynthesis , cov nroj tsuag hloov radiant zog los ntawm hnub mus rau chemical zog nyob rau hauv daim ntawv ntawm qabzib - los yog qab zib. Cov nroj tsuag noj hauv dej, carbon dioxide, thiab hnub ci thiab tig lawv rau hauv qabzib thiab oxygen.
Tom qab ntawd, lo lus nug yog, yuav ua li cas chlorophyll hloov lub teeb lub zog mus rau lub zog tshuaj? Lub teeb zog yog hloov dua siab tshiab rau chemical zog thaum photochemically zoo siab tshwj xeeb tshuaj chlorophyll molecule ntawm photosynthetic cov tshuaj tiv thaiv chaw poob ib tug electron, nyob rau hauv ib tug oxidation cov tshuaj tiv thaiv.
Ib yam li ntawd, cov khoom siv hluav taws xob twg siv yog tias lawv tsis siv lub hnub lub zog?
Dab tsi yog autotrophs? Autotrophs siv zog los ntawm ib puag ncig los roj lub rooj sib txoos ntawm cov yooj yim inorganic compounds rau hauv complex organic molecules.
Dab tsi yog txheej txheem los ntawm cov kab mob uas siv tshuaj zog los tsim cov carbohydrates?
Tshooj 3: Lub Biosphere
| A | B |
|---|---|
| chemosynthesis | ib qho txheej txheem uas qee cov kab mob siv tshuaj zog los tsim cov carbohydrates. |
| heterotrophs | lub cev uas tau txais lub zog los ntawm cov khoom noj uas nws noj; kuj hu ua tus neeg siv khoom. |
| neeg siv khoom | ib lub cev uas tso siab rau lwm yam kab mob rau nws lub zog thiab khoom noj khoom haus. |

Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Cov ntaub ntawv dab tsi yog siv los faib cov kab mob mus rau hauv cov thawj thiab lub nceeg vaj?
Cell qauv yog siv los faib cov kab mob mus rau hauv Domains thiab Kingdoms. - Cov qauv ntawm tes siv li cas los faib cov kab mob mus rau hauv pawg taxonomic? Cov kab mob tuaj yeem raug cais thiab muab tso rau hauv Domains los ntawm lawv cov yam ntxwv
Nws hu ua li cas thaum lub teeb lub zog hloov mus rau chemical zog?
Photosynthesis. Photosynthesis yog cov txheej txheem los ntawm cov kab mob uas muaj cov xim chlorophyll hloov lub teeb lub zog rau hauv cov tshuaj siv zog uas tuaj yeem khaws cia rau hauv cov khoom sib txuas ntawm cov organic molecules (piv txwv li, suab thaj)
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
Hom molecules twg feem ntau yog siv los ntawm cov kab mob rau quorum sensing?
Cov kab mob Gram-negative thiab Gram-positive siv hom kev sib txuas lus no, txawm hais tias cov teeb liab molecules (auto-inducers) siv los ntawm lawv txawv ntawm ob pawg: Gram-negative bacteria siv feem ntau N-acyl homoserine lacton (AHL) molecules (autoinducer- 1, AI-1) thaum cov kab mob Gram-zoo siv feem ntau peptides (
