Qhov Tseem Ceeb - Archaebacteria vs Eubacteria Cell Phab
Cov kab mob yog pawg loj tshaj plaws ntawm prokaryotes pom nyob rau hauv ntau qhov chaw nyob hauv cov xwm txheej, qee qhov muaj qhov hnyav hnyav, xws li cov cua kub, cov cua kub sulfur springs, thiab lwm yam. Txhua hom kab mob no yog unicellular, tab sis tej zaum yuav tshwm sim li pab pawg ntawm cov hlwb. Cov kab mob tsis muaj cov nucleus thiab cov kab mob uas muaj cov kab mob me me. Lawv cov khoom siv caj ces yog ib puag ncig DNA uas tsis muaj histones ntawm nws. Lawv muaj ntau yam physiological kev ua ub no, uas pab kom lawv ciaj sia nyob rau hauv lub widest ntau yam ntawm substrates. Raws li lawv qhov sib txawv biochemical, cov kab mob tau muab faib ua ob pawg; archaebacteria thiab eubacteria. Archaebacteria yog cov kab mob thaum ub heev uas muaj qee yam tshwj xeeb, thiab lawv txawv ntawm eubacteria nyob rau hauv muaj pes tsawg leeg ntawm cov phab ntsa ntawm tes, daim nyias nyias, thiab cov khoom muaj feem xyuam rau cov protein synthesis. Gram-positive eubacteria thiab archaebacteria muaj cov phab ntsa ntawm tes yooj yim tshaj plaws, uas yog tuab thiab ua los ntawm 90% peptidoglycan, whereas Gram-tsis zoo cov kab mob muaj cov kab mob ntau-txheej cell phab ntsa nrog nyias peptidoglycan txheej (txog 10% ntawm phab ntsa cell) hauv lawv cell phab ntsa. Yog li ntawd, cell phab ntsa tsim los ntawm peptidoglycan yog qhov tseem ceeb heev los txheeb xyuas qee hom kab mob los ntawm Gram staining method. Qhov sib txawv tseem ceeb ntawm archaebacteria cell phab ntsa thiab eubacteria cell phab ntsa yog qhov tsis muaj muramic acid thiab D-amino acids nyob rau hauv lub cell phab ntsa ntawm archaebacteria. Tsis tas li ntawd, muaj qee qhov sib txawv ntawm cov qauv thiab tshuaj lom neeg sib txawv ntawm cov phab ntsa ntawm tes ntawm ob pawg no. Hauv tsab xov xwm no, qhov sib txawv ntawm cov phab ntsa ntawm tes ntawm archaebacteria thiab eubacteria tau tham txog kom meej.
Archaebacteria Cell Phab
Archaebacteria yog pawg kab mob qub tshaj plaws uas muaj peev xwm ciaj sia nyob hauv ntau qhov chaw huab cua thiab tsis tuaj yeem nyob hauv qhov xwm txheej. Muaj peb pawg ntawm archaebacteria; Methanogens, halophiles, thiab thermoacidophiles. Archaebacteriapossess qee cov yam ntxwv tshwj xeeb, uas ua rau lawv txawv ntawm eubacteria. Ntawm qhov sib txawv no, qhov pom tshaj plaws yog cov phab ntsa ntawm tes. Tsis zoo li hauv eubacteria, archaebacteria tsis muaj muramic acid thiab D-amino acids hauv peptidoglycan. Lawv cov phab ntsa ntawm tes yog tsim los ntawm cov proteins, glycoproteins lossis polysaccharides. Ob peb genera ntawm archaebacteria muaj cell phab ntsa ua los ntawm pseudomuerin, uas muaj tib lub qauv ntawm eubacterial peptidoglycan, tab sis tseem txawv nyob rau hauv tshuaj muaj pes tsawg leeg.
Eubacteria Cell Phab
Eubacteria yog cov kab mob phototrophic, chemotrophic lossis heterotrophic kab mob uas qhia ntau yam kev ua ub no hauv metabolic. Lawv cov phab ntsa ntawm tes yog tsim los ntawm N-acetylmuramic acid thiab N-acetylglucosamine, nrog cov amino acid linkages.
Qhov txawv ntawm Archaebacteria thiab Eubacteria Cell Wall yog dab tsi?
Composition:
Archaebacteria cell phab ntsa: Archaebacteria cell phab ntsa tsis muaj muramic acid thiab D-amino acids.
Eubacteria cell phab ntsa: Eubacteria muaj ob yam no nrog peptidoglycan.
