Cov cell phab ntsa ntawm gram-positive kab mob yog peptidoglycan macromolecule nrog cov khoom siv txuas ntxiv xws li teichoic acids, teichuronic acids, polyphosphates, lossis carbohydrates (302, 694).
Tib neeg kuj nug, hom carbohydrate ua rau feem ntau ntawm cov kab mob ntawm cov phab ntsa?
Kab mob cell phab ntsa yog ua ntawm peptidoglycan (tseem hu ua murein), uas yog ua los ntawm polysaccharide chains cross-linked los ntawm txawv peptides uas muaj D-amino acids. Kab mob cell phab ntsa txawv ntawm cov cell phab ntsa ntawm cov nroj tsuag thiab fungi uas yog ua ntawm cellulose thiab chitin, feem.
Ib yam li ntawd, cov kab mob cell phab ntsa yog dab tsi? A cell phab ntsa yog ib txheej nyob sab nraum lub cell membrane pom nyob rau hauv cov nroj tsuag, fungi, kab mob , algae, thiab archaea. Ib tug peptidoglycan cell phab ntsa muaj li ntawm disaccharides thiab amino acids muab kab mob kev txhawb nqa. Cov kab mob cell phab ntsa feem ntau yog lub hom phiaj rau kev kho tshuaj tua kab mob.
Ib sab ntawm qhov no, cov amino acid twg pom tsuas yog hauv cov phab ntsa ntawm tes ntawm cov kab mob?
Diaminopimelic acid
Puas yog tag nrho cov kab mob muaj cov phab ntsa ntawm tes?
Hauv feem ntau cov kab mob , a cell phab ntsa yog muaj nyob rau sab nraum lub cell membrane . Cov cell membrane thiab cell phab ntsa suav nrog cell hnab ntawv. Ib qho kab mob cell phab ntsa Cov khoom siv yog peptidoglycan, uas yog tsim los ntawm polysaccharide chains cross-linked los ntawm peptides uas muaj D-amino acids.

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
Vim li cas cov phab ntsa ntawm tes tsis muaj nyob hauv cov tsiaj hlwb?
Tsiaj cells tsis muaj cov phab ntsa ntawm tes vim lawv tsis xav tau. Cell phab ntsa, uas muaj nyob rau hauv cov nroj tsuag hlwb, tswj cov cell zoo li, yuav luag txhua cell muaj nws tus kheej exoskeleton. Qhov rigidity no tso cai rau cov nroj tsuag tuaj yeem sawv ntsug yam tsis xav tau cov pob txha
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
Hom phab ntsa ntawm tes ua cov kab mob fungi?
Zoo li cov nroj tsuag, cov kab mob fungal muaj cov phab ntsa tuab. Cov khaubncaws sab nraud povtseg ntawm fungal cell phab ntsa muaj complex polysaccharides hu ua chitin thiab glucans. Chitin, kuj pom nyob rau hauv lub exoskeleton ntawm kab, muab cov yam ntxwv lub zog rau lub cell phab ntsa ntawm fungi. Phab ntsa tiv thaiv lub cell ntawm desiccation thiab predators
Cov kab mob twg muaj peptidoglycan hauv lawv cov phab ntsa ntawm tes?
Tshooj 18: Kev faib tawm A B Cov kab mob ib feem ntawm unicellular prokaryotes uas muaj cov phab ntsa ntawm tes uas muaj peptidoglycans Eubacteria lub nceeg vaj ntawm unicellular prokaryotes uas nws cov phab ntsa ntawm tes yog tsim los ntawm peptidoglycan Archaea ib feem ntawm unicellular prokaryotes uas muaj cellept phab ntsa uas tsis muaj peptidoglycan
