The Schnakenberg Reaction

In 1979, J. Schnakenberg introduced a system showing sustained oscillations for a simple model of glycolysis (a metabolic process that converts glucose to provide energy for metabolism), very similar to a system known as the "Brusselator" that consists of four reactions.

The reaction is trimolecular and involves autocatalysis: the reaction product is itself a catalyst for one step of the reaction. The reaction proceeds in three steps:
following the kinetic equations
