YProkaryotic vs Eukaryotic Flagella
Qee lub hlwb eukaryotic thiab prokaryotic tau so ntev zoo li appendages lossis projections hu ua flagella. Cov qauv no yog qhov tseem ceeb hauv kev ua haujlwm ntawm ob leeg eukaryotic thiab prokaryotic hlwb. Txawm hais tias txoj haujlwm zoo ib yam, muaj qee qhov sib txawv ntawm eukaryotic thiab prokaryotic flagella. Lawv feem ntau txawv ntawm cov protein muaj pes tsawg leeg, qauv, thiab kev ua haujlwm mechanism.
YProkaryotic Flagella
Prokaryotic flagella yog cov qauv yooj yim heev thiab yog tsim los ntawm ib qho fiber ntau ntawm flagellin protein, uas muaj 53KDa subunit. Cov lus tsa suab ntawm Prokaryotic flagella yog whirling zoo li los yog tig zoo li. Cov kab mob flagella feem ntau pom tsuas yog nyob rau hauv lub tshuab ntsuas hluav taws xob thiab nyob rau hauv tag nrho sab nraud ntawm cov plasma membrane.
YEukaryotic Flagella
Cov qauv ntawm eukaryotic flagellum yog txoj hauv kev, thiab nws muaj 9 + 2 microtubule qauv. Lub flagellum ntawm eukaryotes feem ntau yog nyob ib puag ncig ntawm cell membrane thiab muaj li ntawm tubulin. Cov lus tsa suab ntawm eukaryotic flagella yog so zoo li lossis "S" zoo li. Cilium yog lwm appendage uas zoo ib yam li flagella uas muaj nyob rau hauv eukaryotic hlwb. Feem ntau eukaryotic cell muaj txog ib lossis ob lub flagella. Sperm cell yog ib qho piv txwv rau flagellated eukaryotic cell, thiab txav los ntawm ib qho flagellum. Eukaryotic flagella muaj zog hauv kev txav nrog kev pub mis thiab kev xav.
Qhov txawv ntawm Prokaryotic thiab Eukaryotic Flagella yog dab tsi?
• Prokaryotic flagella yog me dua thiab yooj yim hauv cov qauv, whereas eukaryotic flagella yog qhov loj dua thiab nyuaj hauv cov qauv.
• Prokaryotic flagella yog tsim los ntawm flagellin protein thaum eukaryotic flagella yog ua los ntawm tubulin.
• Lub zog ntawm prokaryotic flagella yog proton tsav, whereas lub zog ntawm eukaryotic flagella yog ATP tsav.
• Prokaryotic flagella muaj rotator txav, whereas eukaryotic flagella muaj blending zog.
• Tsis zoo li prokaryotic flagella, eukaryotic flagella muaj 9 + 2 kev npaj ntawm microtubules.
• Prokaryotic flagella nyob sab nraum lub plasma membrane, whereas lub flagella nyob rau hauv eukaryotes yog them nrog plasma membrane.
