, thiab yog li suav tias yog ib feem ntawm lub hnab ntawv sab nrauv ntawm cov kab mob ntawm tes. Nws yog txheej txheej zoo, tsis yooj yim ntxuav, thiab tuaj yeem ua rau muaj ntau yam kab mob.

Lub tshuaj ntsiav yog dab tsi thiab nws nyob qhov twg?

Capsule nyob tam sim sab nrauv rau murein (peptidoglycan) txheej ntawm cov kab mob gram-positive thiab txheej txheej (Lipopolysaccharide txheej) ntawm cov kab mob gram-negative. Hauv electron microscopy, capsule zoo li lub mesh lossis network ntawm cov hlua zoo.

Pob cov kab mob puas muaj tshuaj ntsiav?

Tsis yog txhua hom kab mob tsim tshuaj ntsiav; Txawm li cas los xij, cov tshuaj ntsiav ntawm cov kab mob encapsulated feem ntau yog qhov tseem ceeb rau kev txiav txim siab ntawm kev ua phem. Encapsulated hom muaj nyob ntawm cov kab mob Gram-positive thiab Gram-negative.

Lub tshuaj ntsiav hauv lub cell yog dab tsi?

Definition. Protein uas yog ib feem ntawm cov tshuaj ntsiav, cov qauv tiv thaiv ib puag ncigkab mob los yog fungi. Cov kab mob capsule yog ib txheej ntawm cov khoom siv, feem ntau polysaccharide, txuas rau ntawm phab ntsa ntawm tes tej zaum los ntawm covalent txuas rau phospholipid lossis lipid-A molecules.

Cov tshuaj ntsiav hauv eukaryotic hlwb yog dab tsi?

Cov tshuaj ntsiav pab prokaryotes cling rau ib leeg thiab rau ntau qhov chaw hauv lawv ib puag ncig, thiab tseem pab tiv thaiv lub cell kom qhuav. Nyob rau hauv cov ntaub ntawv ntawm cov kab mob ua rau prokaryotes uas tau colonized lub cev ntawm ib tug tswv tsev kab mob, cov tshuaj ntsiav los yog slime txheej kuj yuav tiv thaiv tus tswv lub cev tiv thaiv kab mob.
