✦ Synopsis

An explmt pomt method IS described for dwtal snnulatlon of redox-enzyme catalysis and diffislon at soluble-enzyme electrodes Two experImenta conchtlons (chronopotentlometry and open-arcmt potential decay) were sunulated for a two-substrate enzyme (glucose oxldase) catalyzing the anaerobic oxidation of glucose, mechated by a soluble redox couple Tramlent and steady-state responses are compared to expernnental data and to prechctlons of the analyhcal solutions for selected cases Smmlated steady-state concentration profiles near the electrode surface are analyzed for dflerent values of KS/C, and K&C, The vahdlty of hnear Lmeweaver-Burk plots for the amperometnc response of enzyme electrodes IS &cussed &ywor& Amperometry, Enzyme electrodes, Glucose oxldase, DigItal slmulatlon
