Enzyme Catalysis


Learning Objective
List the five typical mechanisms used by enzymes to catalyze biological reactions
Key Points
Enzymes are a special class of catalyst that can accelerate biochemical reactions.
Enzymes are proteins that bind reactants, or substrates, in regions called active sites.
Upon binding, conformational changes in enzymes result in stabilization of the transition state complex, lowering the activation energy of a reaction.
Terms
active siteThe area within an enzyme where the substrate binds.
substrateThe reactant(s) involved in a biochemical reaction catalyzed by an enzyme.
enzymeA globular protein that catalyzes a biological chemical reaction.
Synthetic catalysts are used to accelerate a variety of industrial processes and are crucial to the chemical manufacturing industry. However, catalysts are also found in nature in the form of enzymes. Enzymes are proteins that are able to lower the activation energy for various biochemical reactions. They do this by binding the reactant(s), known as the substrate(s), to an active site within the enzyme. At the active site, the substrate(s) can form an activated complex at lower energy. Once the reaction completes, the product(s) leaves the active site, so the enzyme is free to catalyze more reactions.


Enzyme catalysisAn enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
