Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What kind of receptor is responsible for gustation?
A
Mechanoreceptor
B
Chemoreceptor
C
Photoreceptor
D
None of the above
Explanation: 

Detailed explanation-1: -Examples of direct chemoreceptors include: 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: -Thus, receptor responsible for taste is gustatory lobe. Q.

Detailed explanation-3: -The Gustatory receptors are a divergent group of (non-GPCR) seven-transmembrane chemoreceptors that are expressed in gustatory sensilla receptor neurons. They detect tastants (non-volatile compounds) via contact chemosensation.

Detailed explanation-4: -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.

Detailed explanation-5: -Within the structure of the papillae are taste buds that contain specialized gustatory receptor cells for the transduction of taste stimuli. These receptor cells are sensitive to the chemicals contained within foods that are ingested, and they release neurotransmitters based on the amount of the chemical in the food.
