Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.

Place the letter corresponding to the correct answer in the blank to the left of the reaction.
In the diagram below:
- The starting material is a cyclohexene molecule (a six-membered carbon ring with one double bond).
- The reactant is \( \text{Br}_2 \) (bromine).
- The product is a cyclohexane molecule (a six-membered carbon ring) with two bromine atoms attached to adjacent carbon atoms, indicating that the double bond has been broken and the bromine atoms have been added across the former double bond.
```plaintext
____
(arrow indicating a reaction with Br_2)
[Hexagonal ring with a double bond]
+
[Br_2]
=
[Cyclohexane ring with two Br atoms attached to adjacent carbons]
____
```
- Addition reaction
- Elimination reaction
- Substitution reaction
- Rearrangement reaction
**Explanation:**
The given reaction should be classified as an **addition reaction**. In this type of reaction, atoms or groups of atoms are added to a molecule; in this instance, bromine atoms are added across the double bond of the cyclohexene, converting it to a dibromocyclohexane.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdaac3699-bbcf-491f-ae47-6900b381c75d%2Fa5ffb988-0558-44f4-8d86-97c6c903c954%2Fqs0t49h_processed.jpeg&w=3840&q=75)
