> the 3D animated Inner Life of the Cell[1] showing these proteins physically walking Reality is even more interesting. The animation regrettably prioritizes "art" over accuracy and education/misconceptions. Between one "step" and the next, the kinesin "legs" are violently flailing around, and the payload has time to explore the entire configuration space reachable given the tether. Think not of a donkey towing a barge, but of a mouse, its tail tied to a balloon, clinging to a wire, in a hurricane! The nanoscale atomic mosh pit from hell. And IIRC, the "steps" are often backward - forward is merely net more frequent. "Art"... basically "video frames" have been highly selected to tell a bogus narrative, without even a brief hint of a reality check. It's like editing a video of some politician jogging to show unmoving legs and divine levitation. Nanoscale reality is much more fun.
