How does a person distinguish flavors?
On May 24, 2024
Concepts to Consider: It depends on the combinations of the four basic tastes: sweet, sour, salty, bitter, and, a fifth, umami. Taste is also affected by smell, texture, and temperature. Olfaction affects flavor since odors pass from the mouth to the nasal cavity through internal chambers. These tastes activate the signal transduction process that involves a G protein and the second messenger, cyclic AMP.
