| 1. | Active site maintained by tertiary structure |
| 2. | Allosteric site required for inhibition only |
| 3. | Peripheral domain used in transport |
| 4. | C-terminal region used for secretion |
| 1. | Enzymes increase the free energy change of reactions |
| 2. | Enzymes are highly specific due to tertiary structure |
| 3. | Enzymes always function at neutral pH |
| 4. | Enzymes convert endergonic reactions into exergonic ones |
