摘要：
A mathematical model for facilitated transport in asymmetric membranes with fixed site carriers was derived by assuming concentration fluctuation and an analogy between electron transport in resistor-capacitor circuit and mass transport in an asymmetric membrane of facilitated transport. In order to examine the validity of the model, bovine serum albumin fixed membranes were fabricated and experiment of facilitated transport of bilirubin was carried out in diffusion cell. The agreement between the theoretical and experimental results is exceptional.
