What is the definition of a competitive enzyme inhibitor?

A competitive enzyme inhibitor is a molecule which has a similar structure to the target molecule (substrate). It acts by binding to and blocking the active site of the enzyme. This prevents the substrate from binding and forming an enzyme-substrate (E-S) complex. Therefore slowing down or completely stopping the reaction.
