The receptors responsible for the senses of taste and smell are
Correct answer: B. chemoreceptors
- A. mechanoreceptors
- B. chemoreceptors
- C. photoreceptors
- D. thermoreceptors
Explanation
Taste buds and the olfactory epithelium respond to dissolved or volatile chemicals, which is the defining feature of chemoreceptors. Both senses feed closely into each other, which is why food seems tasteless when the nose is blocked.

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.
