Enzymes
| Question | Answer |
|---|---|
| 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 |
