Transition state structure of the substrate formed during an enzymatic reaction is:
1. | permanent but unstable | 2. | transient and unstable |
3. | permanent and stable | 4. | transient but stable |

1. | The rate of reaction initially increases with an increase in substrate concentration |
2. | It speeds up the rate of reaction by decreasing the requirement for activation energy |
3. | If the associated co-factor is removed, the enzyme activity is enhanced |
4. | Enzymes have an optimum temperature and pH at which they act most efficiently |
The substrate has to go through a higher energy state or transition state during its conversion to a product in:
I: | Exothermic spontaneous reactions |
II: | Endothermic reactions |
III: | Enzyme catalyzed reactions |
1. | Only I and II |
2. | Only I and III |
3. | Only II and III |
4. | I, II, and III |
