NONLINEAR DYNAMICS IN CLOSED BIOLOGICAL AND CHEMICAL-SYSTEMS

In cell free extracts of yeast, glycolysis exhibits nonlinear temporal behaviour, in response to the infusion rates of metabolisable sugars. Such bistability in closed systems is difficult. In the closed system , the glycogen induced nonlinear behaviour in cell free extracts of Sa ccharomyces carlsbergensis are described and the control characteristi cs are evaluated. In closed chemical systems involving acidic bromate, reactions exhibit both linear and nonlinear oxidation kinetics depend ing on the nature of the participating reactants. Taking the appropria te examples, the nonlinear and the steady state behaviour in the acidi c bromate systems is discussed.
