Experiments with genetically modified mice indicated that the mice would swallow abnormally high quantities of bitter-tasting compounds in water after their sweet-taste cells existed altered to express receptors for bitter tastings, indicating that the sense of taste relies only on which taste cell exists enabled.
Psychophysics studies the connection between the physical nature of stimuli and the sensory responses they evoke.
Type II cells convey G-protein coupled receptors (GPCRs) to notice sweet, umami, and bitter flavors. Type III cells sense sour stimuli, while Type IV cells probably convey stem or progenitor taste cells.
Experiments with genetically modified mice indicated that the mice would swallow abnormally high quantities of bitter-tasting compounds in water after their sweet-taste cells existed altered to express receptors for bitter tastants, indicating that the sense of taste relies only on which taste cell exists enabled.
Therefore, the correct answer is option D. sweet-taste cells existed altered to express receptors for bitter tastants, indicating that the sense of taste relies only on which taste cell exists enabled.
