Question

Which of the following statements is correct about receptors?

• A. Gustatory receptors detect taste while olfactory receptors detect smell.
• B. Both gustatory and olfactory receptors detect smell.
• C. Auditory receptors detect smell and olfactory receptors detect taste.
• D. Olfactory receptors detect taste and gustatory receptors smell.

Answer 1

The correct option is A

Gustatory receptors detect taste while olfactory receptors detect smell.

The correct option is A.
Explanation for the correct option:

1. Receptors are protein-based chemical structures used in biochemistry and pharmacology that receive and translate signals that may be incorporated into biological systems.
2. Gustatory receptors are found on the tongue's papillae and are utilized to sense flavor.
3. The olfactory epithelium of the nasal cavity contains olfactory receptors.
4. These are used to identify different odors.
5. These receptors use sensory nerves to transmit sensory messages to the brain.
6. The sensory organ that perceives taste and flavor is known as the gustatory system.
7. The gustatory system in humans is made up of the gustatory cortex, multiple cranial nerves, and taste cells in the mouth that detect the five flavors of salty, sweet, bitter, sour, and umami.
8. G-protein-coupled receptors (GPCR) are a superfamily of sensory receptors that predominantly detect and react to light, taste, and smell.

Explanation for the incorrect options:
Option B:

1. Gustatory receptors are found on the tongue's papillae and are utilized to sense flavor.
2. The olfactory epithelium of the nasal cavity contains olfactory receptors.
3. These are used to identify different odors.
4. Olfactory receptors can detect airborne scent molecules that enter the nasal cavity and bind to them.
5. Olfactory receptor neurons deliver an impulse to the brain's olfactory system when olfactory receptors are activated.
6. Olfactory receptors (ORs), often referred to as odorant receptors, are chemoreceptors that are expressed in the cell membranes of olfactory receptor neurons.
7. They are in charge of detecting odorants, or substances with an odor, which are what cause the sense of smell to be experienced.

Option C:

1. In order to direct behavior, including orienting movements to acoustical inputs and intraspecies communication, the auditory system converts sound waves into unique patterns of brain activity.
2. The organ of Corti contains the auditory hair cells.
3. There are supporting cells in addition to outer hair cells, which serve to "tune" the cochlea, and inner hair cells, which are the auditory receptors.

Option D:

1. Airborne scent molecules that reach the nasal cavity and bind to olfactory receptors can be detected by olfactory receptors.
2. Olfactory receptor neurons deliver an impulse to the brain's olfactory system when olfactory receptors are activated.
3. Gustatory receptors are another name for taste receptors.
4. The five basic flavors that taste receptors may detect are umami, salty, sour, sweet, and bitter.
5. The tongue's ion channels are employed to detect sour and salty flavors.
6. The detection of umami, bitter, and sweet tastes is carried out by G protein-coupled taste receptors.

Final answer: The correct statement is Gustatory receptor detects taste while olfactory receptors detect smell.
