1. | Oxidoreductases | 2. | Hydrolases |
3. | Ligases | 4. | Lyases |
Assertion (A): | Secondary metabolites in plants do not play any roles in the plant bodies. |
Reason (R): | All secondary metabolites are excretory products in plants. |
1. | Both (A) and (R) are True and (R) correctly explains (A). |
2. | Both (A) and (R) are True and (R) does not correctly explain (A). |
3. | (A) is True; (R) is False |
4. | Both (A) and (R) are False |
Assertion (A): | The effect of competitive inhibition can be overcome by increasing the substrate of the enzyme. |
Reason (R): | The presence of a competitive inhibitor can decrease the rate of enzyme-catalyzed reaction by blocking the substrate from binding to the enzyme. |
1. | Both (A) and (R) are True and (R) correctly explains (A) |
2. | Both (A) and (R) are True but (R) does not correctly explain (A) |
3. | (A) is True but (R) is False |
4. | (A) is False but (R) is True |
