PH Each enzyme has an optimum pH range Changing the pH outside of this range will slow enzyme activity Extreme pH values can cause enzymes to denature. If the pH falls as temperature increases this does not mean that water becomes more acidic at higher temperatures A solution is acidic if there is an excess of hydrogen ions over hydroxide ions ie pH pOH.
