What are enzymes? | Enzymes are important proteins found in living things An enzyme is a protein that reduces the activation energy of a chemical reaction |
What are of an enzyme fits the substrate? | Active site |
Substrates undergo chemical changes to form new substances called? | Products |
Enzymes only interact with what? | Specific substrates |
Enzymes do what? | Speed up reaction |
Enzymes reactions can be what? | slowed down or speeded up by factors, such as temperature, pH, substrate and inhibitors. |
Enzymes can be used how many times? | Over and Over again if they maintain their shape |
Enzymes are involved in what processes? | Enzymes are involved in nearly all metabolic processes |
What is Metabolism? | The chemical processes that occur within a living organism in order to maintain life |
The activities of enzymes depend on what? | Temperature, Ionic conditions, and the PH |
What does an enzyme do? | An enzyme enables molecules called substrates to undergo chemical changesto form new substances called products |
Substrates are the what of chemical reactions? | Subtrates are the reactants of chemical reactions |
Describe an enzyme? | an enzyme has an area called the active site on its surface that fits the shape of the substrate |
What is activation energy | Energy require to imitate a chemical reaction or process |
How does catalysts speed up a chemical reaction? | When energy levels of a molecule decrease the quicker the reaction will take place |
What is the Hypothesis that helps explain enzyme functioning? | Lock and Key |
Enzymes control this aspect of chemical reactions? | The rate |
