31. The lesser palatine nerve synapses at the soft palate and controls sparse taste receptors and mucus glands. 32. TAS2R31 is also expressed in the smooth muscle of human airways, along with several other bitter taste receptors . 33. Synthetic sweeteners such as saccharin activate different GPCRs and induce taste receptor cell depolarization by an alternate pathway. 34. TAS2R10 is also expressed in the smooth muscle of human airways, along with several other bitter taste receptors . 35. TAS2R14 is also expressed in the smooth muscle of human airways, along with several other bitter taste receptors . 36. The charge of the protein also plays an important role in its interaction with the sweet taste receptor . 37. Research has shown this could be because of the different pressure conditions in flights, which alter taste receptors . 38. ENaC can furthermore be found in taste receptor cells, where it plays an important role in salt taste perception. 39. Rhinophores are scent or taste receptors , also known as chemosensory organs situated on the dorsal surface of the head. 40. Taste receptors of the T1R family, belonging to the same class of GPCR as metabotropic glutamate receptors are involved.
