WebApr 2, 2024 · Flagella are powered by electric nanomotors, the flagellar motors, which generate a torque proportional to the proton motive force (pmf) across the cell's inner membrane. In cells expressing proteorhodopsin, when oxygen concentration is low and respiration is inhibited, the proton motive force can be regulated from zero to saturation … WebMar 28, 2024 · Abstract. The bacterial flagellar motor is a nanometer-sized rotary motor that generates the torque to drive the rotation of the flagellar filament. The output torque is an important property of the motor. The motor rotation was usually monitored by attaching a μm-sized bead to a shortened flagellar filament, and the torque was extracted by ... bimonte \u0026 crizbi - whenever wherever
