"Web1 de jan. de 2007 · In general, activation energies for enzyme-catalysed reactions are within the range of 25- 63 kJ mol -1. Thus, catalase is not only more efficient than inorganic catalysts such as iodide, but also an exceptionally efficient enzyme. A low value of activation energy implies high efficiency of molecular collisions to form products. " - How can enzymes lower activation energy

How can enzymes lower activation energy

WebEnzymes function to reduce the activation energy required for a chemical reaction to occur. First, the enzyme binds to the substrate and slightly distorts its shape. The change in shape activates the substrate molecule and decreases the total activation energy required for the substrate to be turned into product. WebEnzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that …
