WebEnzymes can be deactivated by a range of factors. Often, this happens because of changes in temperature or pH. Enzymes are picky. Each enzyme has a small range of temperatures and pH levels at which it works best. We call this optimum pH and optimum temperature. If either one falls out of range, the enzyme works much less efficiently.
