Study materials for enzymes
| Question | Answer |
|---|---|
| What does an enzyme/catalyst do to a chemical reaction? | Speeds it up. |
| How do enzymes speed up reactions? | by lowering the activation energy required to start the reaction |
| What does "optimum temperature" mean? | It is the temperature an enzyme is most effective at |
| If an enzyme from the stomach (3pH) is placed in bleach (12pH), what will happen to the enzyme? | Since it is outside its optimum pH range, it will be denatured and no longer work. The reaction will likely not take place. |
| What does it mean when an enzyme is denatured? | The enzyme is damaged. This may cause the enzyme and substrate to not bond as well, which slows down the reaction. |
| What is the reaction rate of a chemical reaction? | How fast the reaction occurs |
| What is activation energy? | The energy required to start a reaction. |
| What three letters do most enzymes end in? | "ase" |
| Enzymes are what kind of macromolecule? | proteins |
| What is the substance called that binds to an enzyme? | the substrate |
| What area of an enzyme do substrates bind to? | the active site |
| When an enzyme and substrate are bound together, what are they called? | the enzyme-substrate complex |
| What is released from an enzyme after the chemical reaction takes place? | the product(s) |
| How can you measure the effectiveness of an enzyme? | By measuring the amount of products created |
