| enzyme | biological catalyst |
| activation energy | the amount of energy needed to climb the hill in a reaction |
| exothermic reaction | a reaction in which the products have lower bond energy and energy is released |
| endothermic reaction | a reaction in which the products have higher energy and the energy is absorbed |
| reactant | the starting material in a chemical reaction |
| product | what is made during the chemical reaction (ending materials) |
| enzyme-substrate complex | substrate binds to enzyme in active site and bonds are weakened |
| coenzyme | a vitamin or other organic molecule needed for the reaction to occur |
| catalyst | a substance that decreases the activation energy needed to start a reaction |
| chemical reactions | change substances into different substances by breaking and forming chemical bonds |
| substrates | reactants in an enzyme catalyzed reaction |
| inhibitor | a substance that binds to the enzyme and prevents it from binding to substrate |
| temperature, pH | factors affecting enzyme activity |
| homeostasis | living organisms need to maintain constant temperature and pH |
| liver in the enzymes lab provides | the enzyme-catalase |
| hydrogen peroxide in the enzymes lab | reactant (substrate) |
| water and oxygen in the enzymes lab | products |
| active site | the place on the enzyme where the substrate binds |
