Enzymes are proteins which have a tertiary structure and they are very specific- only the correct substrate can combine with the active site of the correct enzyme, thereby producing an enzyme substrate complex. The specificity of the enzyme directly relies on the structure, because the structure dictates what the enzyme is compatible with and what it isn't compatible with the chemical structure of an enzyme relates to the catalytic activity because the active site, a small pocket on the surface if the enzyme, triggers the catalytic process.
