The three types of flagella are bacterial, archaeal, and eukaryotic. The flagella in eukaryotes have dynein and microtubules that move with a bending mechanism. Bacteria and archaea do not have dynein or microtubules in their flagella, and they move using a rotary mechanism. Other differences among these three types are: WebNov 1, 2024 · The flagellar motor changes its rotational direction by swapping interaction sites between the C-ring and the stator ring to switch gears. The flagellar switching model presented here is consistent with the evidence that all switching-related chemotaxis mutations are related with the C-ring proteins rather than the stator unit [ 9 , 59 ].
