• Natural molecular motor
• Effective free energy surface
• Newton trajectory
• Barrier breakdown point
• Unidirectional movement

A schematic model of a natural molecular motor is proposed. It uses the change of the free energy surface to an effective surface as long as the enzyme is active. This effective surface acts as a trapdoor and explains the power stroke in biomotors, as well as its unidirectional movement. Then a thermal relaxation can do the energy transduction of the motor. The model uses Newton trajectories to explain the movement of stationary points on the effective surface.
