Enzyme Proteins that act as biological catalyst
catalyst Substance that speeds up the rate of a chemical reaction
Substrate The reactants of enzyme-catalyzed reactions
Carbonic Anhydrase Enzyme contained in the human bloodstream
Activation Energy Energy needed to get a reaction started.
Enzyme-Substrate Complex A complex composed of a substrate bound to the active site of an enzyme.
Product A chemical substance formed as a result of a chemical reaction.
Competitive Inhibitor A substance that reduces the activity of an enzyme by entering the active site in place of the substrate whose structure it mimics
Non-Competitive Inhibitor A substance that reduces the activity of an enzyme by binding to a location remote from the active site, changing its conformation so that it no longer binds to the substrate.
Active Site The part of an enzyme or antibody where the chemical reaction occurs
Allosteric Site A specific receptor site on some part of an enzyme molecule remote from the active site.
Factors that Affect Enzyme Function Enzyme Concentration, Substrate Concentration, Temperature, pH
Lock and Key Model The model of the enzyme that shows the substrate fitting perfectly into the active site.
Induced Fit Model The model of the enzyme that shows the substrate binding to the active site and the active site altering slightly.
Allosteric Inhibitor Molecule binds to an enzyme somewhere other than active site and inhibits.
Reversible Inhibition Inhibition that can be reversed because the enzyme inhibitor attaches with weak bonds
Irreversible Inhibition When an inhibitor attaches to an enzyme with strong covalent bonds and permanently inactivates it.
Feedback Inhibition A method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway.
Edward Buchner Said that enzymes can function Independently
J.B Sumner First to identify an Enzyme as a protein
Digestive Enzymes Catabolic enzymes that are responsible for breaking down food into nutrients and energy
Cofactor A non-protein enzyme component, such as a mwtal ion or an organic compound
Coenzyme cofactors that are organic compounds
Optimal Enzyme Activity Enzymes are both products of evolution and specifically adapted to certain uses in certain areas
Endoenzyme An enzyme found and used within a cell
