Chapter U2.41, Problem 1E

Interpretation Introduction

Interpretation:

Receptor site theory must be explained. Also, this is to be explained how it is applied to the detection of the smell.

Concept introduction:

Smell is a complex process taking place between nasal receptor and odoring molecule.

There are many receptors in nose which can bind with molecules having characteristic smell.

Answer to Problem 1E

Receptor site theory considers that the interaction between molecules takes place in specific manner where all molecules will not fit.

Explanation of Solution

Receptor site theory is very much helpful in explaining the chemistry behind the smell.

Smell is obtained only when molecules from a substance reach to the nasal receptors and bind in a specific manner. Proper matching of the molecules with the cavity of the receptors is required.

Conclusion

Receptor site theory is useful in explaining the smell detection process.
