WebChemical Kinetics • The speed at which reactions take place is called reaction rate. • Some reactions are fast, while other reactions are slow. • Chemists study the rates of reactions … WebEnzymes are reusable. 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.
