Why do basal body of bacterial flagella considered as smallest motor in the world?

Answer»

1. The bacterial flagellum is an organelle for motility made up of three parts: 

a. The basal body that spans the cell envelope and works as a rotary motor; 

b. The helical fdament that acts as a propeller;

c. The hook that acts as a universal joint connecting these two to transmit motor torque to the propeller. 

2. The motor i.e. basal body drives the rotation of the long, helical filamentous propeller at hundreds of hertz to produce thrust that allows bacteria to swim in liquid environments. Therefore, basal body of bacterial flagella considered as smallest motor in the world.
