Chemosynthetic kab mob yog kab mob uas siv inorganic molecules los ua ib qhov chaw ntawm lub zog thiab hloov mus rau hauv cov organic tshuaj. Chemosynthetic kab mob Tsis zoo li cov nroj tsuag, tau txais lawv lub zog los ntawm oxidation ntawm inorganic molecules, tsis yog photosynthesis.
Tsuas yog li ntawd, qhov piv txwv ntawm cov kab mob chemosynthetic yog dab tsi?
Piv txwv ntawm chemoautotrophs suav nrog cov kab mob thiab cov methanogenic archaea nyob hauv cov qhov dej tob hauv hiav txwv. Lo lus " chemosynthesis " yog Ameslikas coined los ntawm Wilhelm Pfeffer nyob rau hauv 1897 los piav txog lub zog tsim los ntawm oxidation ntawm inorganic molecules los ntawm autotrophs (chemolithoautotrophy).
Qhov thib ob, hom kab mob chemosynthetic twg muaj? Hom Chemosynthetic Bacteria
- Cov kab mob sulfur. Cov piv txwv sib npaug rau chemosynthesis muab los saum toj no qhia cov kab mob uas siv cov sulfur compound ua lub zog.
- Hlau Ion kab mob. Hom kab mob uas paub zoo tshaj plaws uas siv hlau ions rau chemosynthesis yog cov kab mob hlau.
- Cov kab mob Nitrogen.
- Methanobacteria.
Ua li no, cov kab mob chemosynthetic autotrophic yog dab tsi?
chemosynthesis Ib hom autotrophic khoom noj khoom haus uas kab mob (hu ua chemoautotrophs) synthesize organic cov ntaub ntawv siv lub zog muab los ntawm oxidation ntawm inorganic tshuaj, es tsis yog los ntawm tshav ntuj.
Cov kab mob chemosynthetic ua zaub mov li cas?
Chemosynthesis yog tus txheej txheem uas zaub mov (glucose) yog tsim los ntawm kab mob siv cov tshuaj ua lub zog, tsis yog hnub ci. Chemosynthesis tshwm sim nyob ib ncig ntawm hydrothermal vents thiab methane seeps nyob rau hauv lub hiav txwv tob uas tsis muaj hnub ci.

Cov kab mob puas kis cov kab mob eukaryotic?
Ib lub cell uas muaj kab mob ua rau cov kab mob kis tau ntau dua thiab cov khoom siv caj ces es tsis yog nws cov khoom qub. Qee cov kab mob yuav nyob twj ywm hauv cov tswv tsev rau lub sijhawm ntev, ua rau tsis muaj kev hloov pauv hauv lawv cov tswv tsev (ib theem hu ua lysogenic theem). Cov kab mob ua rau muaj ntau yam kab mob hauv eukaryotes
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Cov kab mob twg muaj cov kab mob eukaryotic?
Cov kab mob thiab Archaea tsuas yog prokaryotes. Cov kab mob uas muaj eukaryotic hlwb hu ua eukaryotes. Tsiaj txhu, nroj tsuag, fungi, thiab protists yog eukaryotes. Tag nrho cov kab mob multicellular yog eukaryotes
Cov kab mob thiab cov kab mob ua haujlwm zoo li cas?
Ob leeg cov kab mob thiab cov kab mob muaj cov phab ntsa ntawm tes (txawm hais tias sib txawv hauv cov qauv thiab muaj pes tsawg leeg) Feem ntau cov kab mob thiab cov kab mob tau txais lub zog los ntawm kev ua pa aerobic (ua pa hauv cov kab mob me ntsis txawv dua li hauv Eukaryotes tab sis cov pa oxygen ib txwm xav tau rau oxidise suab thaj, hauv dej kawg. thiab carbon dioxide yog tsim)
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
