Did Catalase Denature Temperature?

Once the temperature of catalase exceeds 37°C, it will denature and H₂O₂ molecules probably cannot fit into the active sites and start decreasing the rate of reaction as shown in Figure1. Perhaps from approximately 50°C, there may be no reaction at all, for by then, all catalase will be entirely denatured.

Does catalase change with temperature?

The effects of catalase, like those of all enzymes, are influenced by the surrounding temperature. ... As the temperature increases toward the optimum point, hydrogen bonds loosen, making it easier for catalase to act on hydrogen peroxide molecules.

What temperature does catalase stop?

In conclusion, catalase enzymes work best at temperatures around body temperature (37.5°C), and do not work as well around temperatures 30°C or lower, or 45°C or higher.
