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 ... WebBacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. ... the overlook at geer tree farm griswold ct https://tangaridesign.com
