Cov kab mob flagellum yog helical filamentous organelle lub luag haujlwm rau kev txav mus los… Lub flagellar lub cev muaj zog yog tsim los ntawm lub nplhaib rotor complex thiab ntau yam transmembrane stator units thiab hloov cov ion flux los ntawm ib qho ion. channel ntawm txhua lub tsev stator rau hauv kev ua haujlwm txhua yam yuav tsum tau ua rau lub cev muaj zog tig.
Vim li cas flagella txav?
Eukaryotic Flagella Siv ATP to Khoov Cov dynein molecules siv lub zog los ntawm adenosine triphosphate (ATP), lub zog khaws cia molecule, los tsim kev khoov hauv lub flagella. Cov dynein molecules ua rau flagella khoov los ntawm kev txav cov microtubules nce thiab nqis tawm tsam ib leeg.
flagella mediated motility yog dab tsi?
Flagella-mediated motility yog tseem ceeb rau cov kab mob txav mus rau hauv kev tshawb nrhiav chaw nyob zoo duathiab ob hom tau paub txog hnub no: (i) "khiav thiab tumbling" pom hauv peritrichous kab mob xws li Escherichia coli; thiab (ii) "forward run-reverse-flick" pom hauv Vibrio alginoliticus.
Puas yog flagella tsis motile?
Cov qauv ntawm tes uas muab lub peev xwm rau kev txav chaw yog cilia thiab flagella. Coliform thiab Streptococci yog cov piv txwv ntawm tsis-mob cov kab mobxws li Klebsiella pneumoniae, thiab Yersinia pestis.
Txoj kev npaj flagella twg yog qhov zoo tshaj plaws?
Flagella yog cov qauv muaj protein ntau txuas rau ntawm lub xov tooj ntawm tes uas muab kev ua luam dej rau feem ntau ntawm cov procaryotes. Procaryotic flagella yog thinner dua eucaryotic flagella, thiab lawv tsis muaj "9 + 2" kev npaj ntawm microtubules.
