Non-Equilibrium Dynamics, Biological Systems and Time-Arrow

Pp. 184-195 (12)

Jacques Ricard

Abstract

The concept of time-arrow does not appear frequently in physics. This is not the case for the study of biochemical systems as many of them are able to sense whether a variable is increasing or decreasing. This effect can be explained by the non-linear character of the system and its dynamics.

Keywords:

Bound enzymes and hysteresis loops, Time-arrow and non-linearity of sequences of biochemical reactions, Non-linearity and sensing chemical signals, Sensing the direction of a process.
