 This follows the work of Wolf and Hierich (1), which takes a simple model of glycolytic oscillations (2) as the base unit (a cell with oscillating glycolysis) and creates a new model with suspensions consisting of an arbitrary number N of interacting units. The individual cells interact via the flux of metabolites, which are produced in all cells and may permeate through the cell membranes (1). Two specific cases are examined: in Model I the coupling is via the product of the autocatalytic reaction (species Y), and in Model II the coupling is via the substrate of the autocatalytic reaction (species X).
