A catalyst is a substance that speeds up the rate of a chemical reaction without itself being consumed or generated by the reaction. An enzyme is a protein that acts as a catalyst. The term substrate refers in enzymology to a reactant in an enzyme-catalyzed reaction.

WebThe competitive inhibitor binds to the active site and prevents the substrate from binding there. The noncompetitive inhibitor binds to a different site on the enzyme; it doesn't block substrate binding, but it causes other changes in the enzyme so that it can no longer catalyze the reaction efficiently.
