Question
Compared to sensory receptors in the eyes and ears, the senses of gustation and olfaction are somewhat unique in that their receptors are sensitive to ____________ rather than to ___________.Group of answer choicesA. some form of energy; chemical moleculesB. sounds; some form of energyC. chemical molecules; some form of energyD. light; sounds
Solution
The correct answer is C. Chemical molecules; some form of energy.
Here's why:
-
Sensory receptors in the eyes and ears are sensitive to some form of energy. In the eyes, photoreceptor cells in the retina respond to light energy. In the ears, mechanoreceptors respond to mechanical energy in the form of sound waves.
-
On the other hand, the senses of gustation (taste) and olfaction (smell) are unique because their receptors are sensitive to chemical molecules.
-
In gustation, taste buds on the tongue contain gustatory cells that respond to chemical molecules in food. These molecules bind to receptors on the gustatory cells, triggering a response.
-
In olfaction, olfactory cells in the nose respond to chemical molecules in the air. These molecules bind to receptors on the olfactory cells, triggering a response.
So, compared to sensory receptors in the eyes and ears that respond to some form of energy, the senses of gustation and
