Question

The membrane proteins that respond to chemical stimuli to produce sweet, bitter, and umami sensations are called A) photoreceptors. B) proprioceptors. C) nociceptors. D) transducins. E) gustducins.

Answer 1

Gustducins are the membrane proteins that respond to chemical stimuli to produce taste sensations such as sweet, bitter, and umami.

Step-by-step explanation:

The membrane proteins that respond to chemical stimuli to produce sweet, bitter, and umami sensations are called gustducins.

Gustducins are found in taste receptor cells on the tongue and are responsible for transducing the chemical signals of different taste sensations to the brain.

For example, sweet taste receptors on the taste buds contain gustducins that respond to sugars and artificial sweeteners, while bitter and umami taste receptors have gustducins that respond to different types of molecules.
