分子马达在以布朗运动为主的环境中运行时将化学能转化为机械功。本文的目的是探索分子马达与其周围环境之间的能量流动,特别是其效率。基于非无限化学态的Fokker-Planck方程,我们发现分子马达的能量效率,无论是斯托克斯效率还是通常的热力学效率,都严格小于1,因为能量在过阻尼环境和化学反应过程中都有耗散。
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.
