Study Notes
Bacterial Flagella
- Rotation Power Source: The rotation of bacterial flagella is powered by the proton motive force (PMF), a gradient of protons across the membrane.
- Function of Rotation: Flagellar rotation enables bacteria to move towards or away from stimuli, a process known as chemotaxis, allowing them to respond to their environment.
Flagella Structure and Arrangement
- Arrangement: Bacterial flagella are typically arranged in a polar or peritrichous manner, with flagella located at the poles or scattered all over the cell surface.
- Structure: A flagellum consists of three main parts: the filament, hook, and basal body, with the filament being the long, helical structure responsible for propulsion.
