The transport of Brownian particles moving along a three-dimensional fluctuating tube is investigated in the presence of a load. The tube wall can fluctuate between two states. Coarsening the description of a process for the sake of simplifying the dynamic will result in an entropic barrier and an effective diffusion coefficient. It is found that we can control the asymmetric parameter and the load force to control the current direction and there is an optimized transition rate at which the current takes a maximum value.
