Enzymes
| Question | Answer |
|---|---|
| Enzymes | Proteins that act as biological catalysts. |
| catalysts | a substance that speeds up the rate of chemical reaction. |
| substrates | the reactants of enzyme-catalyzed reactions. |
| Carbonic Anhydrase | enzyme that speeds up the reaction by a factor of 10 million. |
| Active sight | Energy needed to get reactions started |
| Enzyme-substrate complex | A complex composed of a substrate bound to the active sight of an enzyme |
| product | a chemical substance formed as a of a chemical reaction |
| Activation Energy | Energy that is need to get a reaction started |
| Irreversible Inhibition | When an inhibitor attaches to an enzyme with strong covalent bonds and permanently inactivates it. |
| Reversible Inhibition | Inhibition that can be reversed because the enzyme inhibitor attaches with weak bonds. |
| Allosteric Inhibitor | Molecule binds to an enzyme somewhere other than active site and inhibits. |
| Induced Fit Model | The model of the enzyme that shows the substrate binding to the active site and the active site altering slightly. |
| Lock and Key Model | The model of the enzyme that shows the substrate fitting perfectly into the active site. |
| Allosteric Site | A specific receptor site on some part of an enzyme molecule remote from the active site. |
| 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. |
| 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. |
| Cofactor | A non-protein enzyme component, such as a metal ion or an organic compound, is called a cofactor |
| Coenzyme | Coenzymes are cofactors that are organic compounds. |
| Optimal enzyme activity | Enzymes are both products of evolution and specifically adapted to certain uses in certain environments (often intracellular). A "cost" of such specificity is that activity tends to decline. |
| Endoenzyme | An enzyme found and used within a cell. |
| Exoenzyme | An enzyme secreted into the extracellular environment for use there, for example, in hydrolyzing polysaccharides to the monosaccharides which may then be taken up by cells and used. |
| Edward bunchner | said that enzymes can function independently |
| digestive enzymes | catabolic enzymes that are respobisible for breaking down food into nutrients and energy. |
| J.B sumner | first to identify an enzyme as a protein |
