Enzymes
| Term | Definition |
|---|---|
| Enzyme | A biological catalyst and is almost always a protein that speeds up the rate of a specific chemical reaction in the cell. |
| Catalyst | any substance that speeds up or slows down the rate of a chemical reaction |
| The suffix (last three letters) that enzymes end with. | -ase (example: lipase, protease, lactase) |
| Substrate | The substance (reactant) an enzyme act on. |
| Active Site | the specific area of an enzyme molecule that links to the substrate molecule and catalyzes its metabolism |
| Denature | Enzymes that no longer have a functional active site because their shape has changed due to heat or pH and they cannot catalyze reactions anymore. |
| Enzymes are made up of | amino acids (proteins) |
| amylase | an enzyme specific for the hydrolysis of starch in simple sugars |
| All enzymes end with the three letters... | -ASE |
| enzymatic hydrolysis | an enzyme-controlled reaction by which complex food molecules are broken down chemically into smaller subunits |
| Lipase | any lipid-hydrolyzing enzyme |
| Lock and Key Model | -a theoretical model of enzyme action that attempts to explain the concept of enzyme specificity -Only a certain shape active site of an enzyme will fit with a specific substrate |
| protease | any protein hydrolyzing enzyme |
| digest | breaking apart a large molecule into its smaller units |
| synthesize | Taking smaller units and combining them to form a larger one |
