Chapter 21, Problem 3STP
Interpretation Introduction

Interpretation: The lock and key model needs to be matched with the correct option.

Concept Introduction:

Enzyme is composed of proteins. This is a substance that performed as catalyst and maintaining the rate of chemical reactions proceed without used in the process.

They act on substrate and formed a complex that is enzyme substrate complex and converted into product.

Expert Solution & Answer
Check Mark

Answer to Problem 3STP

Correct answer: Option (C) the function of the enzymes.

Explanation of Solution

Reason for correct option:

The lock and key model applies for the function of the enzymes, where the enzyme acted as key and substrate is the lock. The interaction of enzyme and substrate is follows the lock and key theory. The interactions of a particular site with the enzyme is called active center. The enzyme substrate complex is formed the product.

Conclusion

Reasons for incorrect options:

Option (A) the structure of carbohydrates in not explain by the lock and key model, hence it is incorrect option.

Option (B) the shape of the proteins is not related to the lock and key model. So it is incorrect for the lock and key model.

Option (D) glycoside linkage is a type of bonding is not explain by the lock and key model. Hence it is incorrect option.
