摘要：

Energy dissipation fulfils an important function in metabolism driving the flux of matter through metabolic pathways. The flux rate is a multivariable function. One of such variables affecting the flux is the actual free energy change. A particular case of metabolic pathway is analysed to illustrate this fact, using only general enzymic and thermodynamic concepts. (C) 2001 IUBMB. Published by Elsevier Science Ltd.
