Final answer:
False, The bending of cilia and flagella is facilitated by the motor protein dynein, whose arms walk along microtubules to produce a sliding motion that results in bending.
Step-by-step explanation:
False, The bending of cilia and flagella is not driven by the arms of a motor protein. Instead, it is powered by the dynein motor protein. Dynein arms are complex protein structures located along the microtubules of cilia and flagella. The dynein arms undergo ATP-driven conformational changes, leading to the sliding of adjacent microtubule doublets. This sliding action between microtubules causes bending and movement of cilia and flagella. The dynein arms serve as molecular motors, converting chemical energy from ATP into mechanical work, ultimately propelling the cilia and flagella to create coordinated, rhythmic movements essential for various cellular and organismal functions.
