bacterial motors

Bacterial motors are microscopic structures that allow bacteria to move. They function like tiny propellers or engines, embedded in the bacteria’s cell membrane. Powered by the flow of ions (such as protons or sodium ions), these motors rotate a tail-like structure called a flagellum. As the flagellum spins, it propels the bacterium forward or enables it to change direction. This motility helps bacteria find nutrients, avoid harm, and colonize environments. Despite their small size, bacterial motors are highly efficient and precisely regulated, making them fascinating examples of nature’s engineering at the microscopic scale.
