WebThe rate of chemical reactions therefore increases with temperature but then decreases as enzymes denature. pH Each enzyme has an optimal pH. A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule change and the molecule changes shape. Webcatalase 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.
