Question
Chapter 27.6, Problem 2MC
Summary Introduction
To determine:
The data that led the researchers conclude that whales cannot taste umami, sweet, bitter, or sour.
Concept introduction:
The taste genes of the whale are present in the cell membrane of the taste receptors cells. These cells contain the protein which is encoded by the taste genes. There are two types of taste genes present in the whales that are T1R (taste receptor type 1) an T2R (taste receptor type 2). The T1R encode for the umami, and sweet taste receptors, and T2R encodes for the bitter taste receptor.

How is the ability to recognize the umami taste an evolutionary advantage? a. Umami identifies healthy foods that are low in salt and sugar. b. Umami enhances the flavor of bland foods. c. Umami identifies foods that might contain essential amino acids. d. Umami identifies foods that help maintain electrolyte balance.
If you can taste only five things (salt, bitter, sweet, sour, umami), why do the many foods you eat all seem so distinct?
Connoisseurs can recognize many varieties of cheese or wine by “tasting.” How can they do so when there are only a few types of taste receptors?
