How do enzymes act as biological catalysts?
An enzyme catalyzes a biochemical reaction by binding a substrate at the active site and after the reaction
has proceeded, the products are released and the enzyme decomposes.
Enzymes lower activation energy, and change the difference in energy levels between reactants and
products.
Chemical reactions occur at the active site of enzymes, where a precise 3D orientation of amino acids is an
important feature of catalysis.
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the
faster the rate.
Activation energy is energy that must be added to get a reaction started, which is recovered as the
reaction proceeds.
Enzymes can catalyze reactions through a variety of ways including destabilizing the bonds within the
substrate.
