If an active-site directed inhibitor is present in the medium, the curve that will represent the progress of the chemical reaction will be shown by the letter:
| 1. D | 2. C | 
| 3. A | 4. B | 
Most common enzyme inhibition used in control of bacterial pathogens is:
| 1. Competitive | 2. Non - competitive | 
| 3. Uncompetitive | 4. Mixed | 
The inhibition of succinic dehydrogenase by malonate is an example of:
| 1. | Non-competitive reversible inhibition | 
| 2. | Non-competitive irreversible inhibition | 
| 3. | Competitive inhibition | 
| 4. | Allosteric inhibition |
