| Question | Answer |
|---|---|
| What is an enzyme? | Catalysts for biochemical reactions. |
| What type of macromolecule is an enzyme? | Enzymes are composed of protein. |
| How do catalysts speed up reactions? | Lower the activation energy of a reaction by providing an alternate pathway |
| What do enzyme names end with? | Enzyme names end in 'ase'. |
| What is the active site of an enzyme? | The region on the enzyme where the substrate binds. |
| What is a substrate? | A molecule upon which an enzyme acts. |
| What is a substrate-enzyme complex? | When the substrate bonds with the enzyme at the active site, an enzyme-substrate complex is formed. |
| What is denaturation? | Structural change in a protein that results in a loss (usually permanent) of its properties. |
| What is a competitive inhibitor? | Occupy the active site and prevent a substrate molecule from binding to the enzyme. |
| What is an end-product inhibitor? | The product of the last reaction in the metabolic pathway that inhibits the enzyme that catalyses the first reaction. |
