Abstract

A particular model of active transport is analyzed, at steady state, by means of a diagram method for the kinetics, and supplemented by use of a free energy diagram. It is assumed that there is cyclic adsorption of adenosine triphosphate (ATP), chemical reaction to adenosine diphosphate (ADP), and desorption of ADP, on a two-state protein (the "carrier"). ATP is the "effector" for the change in state of the protein.

摘要

通过动力学的图解法,在稳态下分析了一种特定的主动运输模型,并辅以自由能图。假设在一种双态蛋白质(“载体”)上存在三磷酸腺苷(ATP)的循环吸附、化学反应生成二磷酸腺苷(ADP)以及ADP的解吸。ATP是蛋白质状态变化的“效应物”。
