Bacterial flagellum structure. Computer artwork of a section through a bacterial cell wall showing the structure of the flagellum base. The flagellum,used for locomotion,is a protein filament designed to rotate like a propeller and move the bacterium forward. The base of the flagellum is composed of a series of rings that allow this helical movement. The entire unit can reach speeds of 200-1000 revolutions per minute. The hook (orange) is the sharp bend in the flagellum where it leaves the cell. Some bacteria have several flagella | |
