KPK 9th Class Biology Chapter 6 Enzymes Short Questions Answers
Differentiate between lock and key model and induced fit model.
| Lock and key model | Induced fit model |
| Active site is a rigid structure | Active is a flexible structure |
| Active site does not change its shape | Active site change their shape slightly |
| Substrate completely complementary in shape to the active site of the enzyme | Substrate not completely complementary in shape to the active site of the enzymes |
In what way does an enzyme affect the chemical reaction it catalyses?
An enzymes affect the chemical reaction, its catalyses by decreased the activation energy.
What will be the effect on digestion if we take some digestive enzymes from outsides?
If we take some digestive enzymes from outside the digestion will be efficiently and effective occurs.
What is means by denaturation of enzymes?
Denaturation of enzymes is the change in enzymes structure due to temperature. This is due to high temperature breaks weak ionic and hydrogen bonding that stabilize the three dimensiobnal structure of enzymes.
How are enzymes specific for the substrate?
Enzymes are specific for the substrate due to the shape of their active sites. The active sites of each enzymes possess specific shapes that fits with the specific substrate.
What are the terms used to describe the temperature and the pH at which an enzymes can work most effectively in a reaction?
The term “optimum” is used to describe the temperature and the pH of which an enzyme works most effectively in a reaction. For example, the optimum temperature for human enzymes is between 35-40. The optimum pH at which most enzymes function best is 6 – 8.
