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.

![**Instruction:**
Highlight the chirality (or stereogenic) center(s) in the given compound. A compound may have one or more stereogenic centers.
**Diagram Explanation:**
The diagram depicts a chemical structure featuring three hexagonal rings connected linearly, resembling a three-ring polycyclic compound. The first (leftmost) and third (middle) rings are cyclohexane rings, and the adjacent second (rightmost) ring is also a cyclohexane ring. Additionally, there is a branched structure attached to the rightmost ring, with a double bond present between the terminal carbon and its neighboring carbon.
When identifying chirality, look for carbon atoms bonded to four different substituents within the structure shown.
In the diagram, various tools are available for annotation, such as a pencil for highlighting, an eraser, and options for undoing and redoing actions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F30851b88-5e79-4818-b8e1-05241e5cb3dc%2F50d7de8c-9e69-4daa-83ca-8eb3d633c856%2Ffw1rjga_processed.jpeg&w=3840&q=75)
