Quizplus · Accepted Answer

Both olfaction (sense of smell) and taste (gustation) require that molecules be dissolved in fluid to interact with their respective receptors. In olfaction, odorant molecules dissolve in the mucus of the nasal cavity to stimulate olfactory receptors. In taste, molecules must dissolve in saliva to interact with taste receptors on the tongue.
