What affects the activation energy of a reaction?

WebBeside above, how do enzymes decrease activation energy? By binding one of the reactants (called a substrate) and keeping it in a manner that lowers 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.
