WebEnzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state. Figure 2.22 Energy diagrams for catalyzed and uncatalyzed reactions. WebEnzymes are proteins that help to speed up chemical reactions. They help to speed up these reactions by decreasing the activation energy for these reactions to occur. Enzymes work at very specific pH and temperature. This is because outside of their optimal range for these two conditions enzymes begin to denature, or change shape. Should an ...
