Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.

WebEnzyme inhibition can be categorized in three types: competitive, noncompetitive, and uncompetitive. Competitive inhibition happens when a compound similar to the substrate is present and competes with the substrate for the active sites of the enzyme obstructing the access of substrate to the active site, thus slowing down the reaction. 37,38
