Chapter 18, Problem 1E

Interpretation Introduction

Interpretation:

The kinds of molecules which are involved in smell are to be listed.

Concept Introduction:

Odor sensation usually depends on the concentration (number of molecules) available to the olfactory receptors. A single odorant stimulus type is typically recognized by multiple receptors, and different odorants are recognized by combinations of receptors, the patterns of neuron signals helping to identify the smell.
