Bistability in the Peroxidase-Oxidase Reaction.

Figure 4. Experimental evidence for bistability. Left. Transition from periodic behavior to a steady state induced by addition (arrow) of H₂O₂. Right. Transition from a steady state to apparently periodic dynamics induced by temporary shutdown (double arrow) of oxygen input. Reproduced from Aguda et al. [af90] with permission. Compare with simulation (Figure 5).
