H₂O₂-induced NO consumption in the presence of Mb. The solid lines represent the NO decay curves after 1 μM NO was injected into the buffer solution, in the buffer solution containing 0.5 μM Mb, and in the buffer solution containing 10 μM H₂O₂. When 1 μM NO was injected into the solution in the presence of 0.5 μM Mb and the peak of the NO oxidation current was reached, the injection of 10 μM H₂O₂ greatly increased the rate of NO decay (dotted line).
