a: Myosin ~
b: a robot walker on an actin racetrack
What: "Myosin is like a robot walker on an actin racetrack. The robot uses ATP for energy. Each stepwise cycle requires ATP hydrolysis, but there is more energy in the action than can be accounted for by the ATP alone. The researchers determined that, as has long been suspected, the structure of the motor allows random thermal motion to be captured as with a ratchet."
