Olfactory receptors are the type of:
Correct answer: D. chemoreceptors
- A. photoreceptors
- B. mechanoreceptors
- C. thermoreceptors
- D. chemoreceptors
Explanation
Smell depends on molecules dissolving in the mucus and binding receptor proteins in the nasal epithelium, so olfactory receptors respond to chemicals and are chemoreceptors, as are the taste buds. Photoreceptors detect light in the retina and mechanoreceptors detect pressure, touch and sound. Classifying a receptor means asking which form of energy or signal it transduces.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
