Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What receptors respond to chemicals and have to do with taste and smell?
A
chemoreceptors
B
photoreceptors
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Taste receptors in the gustatory system: The primary use of gustation as a type of chemoreception is for the detection of tasteants. Aqueous chemical compounds come into contact with chemoreceptors in the mouth, such as taste buds on the tongue, and trigger responses.

Detailed explanation-2: -Chemoreceptors are proteins or protein complexes that bind molecules detected at distance and generally at low concentration (olfaction) or molecules detected at proximity and often at higher concentrations (gustation), respectively volatile and not volatile for organisms living in the aerial phase.

Detailed explanation-3: -Every food or drink that you put in your mouth has particular chemical components, and these chemicals are detected by special receptors called chemoreceptors. These chemoreceptors are contained within taste buds on the surface of the tongue.

Detailed explanation-4: -Chemoreceptors play a major role in the senses of taste and smell. All chemoreceptors are stimulated by the presence of chemicals.

Detailed explanation-5: -The chemoreceptors of taste and smell are closely related; in fact one receptor type, the Lewis acid receptor is common to both the taste (gustatory) and smell (olfactory) modalities.
