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.
![### Molecular Model Identification
#### Model
The diagram on the left shows a molecular model consisting of three spheres connected by sticks, forming a bent or angular shape. This represents the spatial arrangement of atoms within a molecule.
A slider beneath the model ranges from 1 to 8, with the marker set at position 3. This may indicate different molecular structures or views based on the slider's position.
#### Molecules (Check all that apply)
Identify which molecules the model represents by selecting from the following options:
- [ ] BrCN
- [ ] \( \text{O}_3 \)
- [ ] \( \text{N}_3^- \)
- [ ] \( \text{NO}_3^- \)
- [ ] None of the above
#### Explanation
The model presented is a visual representation of a molecule used for educational purposes to help students learn about molecular geometry and structure. It is essential to compare the shape observed with typical molecular structures and select the appropriate molecular formulas given.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa561e43b-9057-4fba-bb36-6896a2421e51%2F73c4e85a-2ae5-46de-a920-8f4fea6c1000%2F7iivqka_processed.png&w=3840&q=75)
