Because of their flexibility, enzymes undergo change in shape at the active site during catalysis itself. north atlantic pelagic advocacy group

"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. " - How do enzymes interact with substrates
