In an experiment, it was found that low concentrations of sodium chloride increase the rate of reaction of catalase and hydrogen peroxide. Would anyone know why this is the case?

If the salt concentration is close to zero, the charged amino acid side chains of the enzyme molecules will attract to each other. The enzyme will denature and form an inactive precipitate. If, on the other hand, the salt concentration is too high, normal interaction of charged groups will be blocked, new interactions will occur, and again the enzyme will precipitate. An intermediate salt concentration such as that of human blood (0.9% ) or cytoplasm is the optimum for many enzymes.

How does salt affect catalase breaking down hydrogen peroxide
