Molecular motors convert chemical energy into mechanical work while operating in an environment dominated by Brownian motion. The aim of this paper is to explore the flow of energy between the molecular motors and its surroundings, in particular, its efficiency. Based on the Fokker-Planck equation with eitherNor infinite chemical states, we find that the energy efficiency of molecular motors, whether the Stokes efficiency or the usual thermodynamic efficiency, is strictly less than one, because of the dissipation of the energy in both the overdamped surroundings and in the process of the chemical reaction.
