title: On exploring the basis for slow and fast oscillations in cellular systems.
abstract: We show that interesting oscillatory patterns may arise from an immobilized enzyme system, when the enzyme has the properties that it is inhibited by a substrate, produces H+ and has a pH-activity curve of bell-shaped form. In agreement with experimental observations in cellular excitations, the system generates fast oscillations that are superimposed on a slow cycle, at certain salt and enzyme concentrations.
