Explanation The gustatory receptors are able to distinguish among the different classes of tastes. The tastes namely, sweet, salty, sour, bitter, and umami are perceived through different pathways. Umami Sour Salty Sweet Bitter The umami taste, which is a savory, meaty kind of a taste is sensed because of the amino acid monosodium glutamate (a flavor enhancer). The sourness of the food is perceived when hydrogen ion (H + ) ions directly affect the sodium ion (Na + ) ions...
