How Flagella Move - Bacteria vs. Eukaryotes - YouTube

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: WebIn the presence of ATP, dynein molecules are activated, and the flagellum bends as dynein arms on one side of a dynein cross-bridge become activated and move up the microtubule. This creates the power stroke. The dynein arms on the opposite side of the dynein cross-bridge are then activated and slide up the opposite microtubule. ts a.s
