The bacterial flagellar motor is a rotary molecular engine driven by an electrochemical gradient; which turns a helical filament generating the thrust enabling the bacteria to swim. The mechanism of torque generation has been described by different models, each of them predicting a different relationship between speed and torque. In order to rule out the less effective models in favor of more p...
