Question

We compared the speed of transduction of the taste of sour vs either sweet or bitter, depending on what you tasted.  Match the taste modality to the most likely transduction mechanism: Ion channel or second messenger system based on what is known. Salty is left out because there is not enough known about it.

Umami

 

Expert Solution
Step 1
  • A taste receptor is a type of cellular receptor found in the taste buds of papillae.
  • When a food substance enters the mouth, it interacts with the saliva, and the chemical compounds in the food bind to the taste receptors in the oral cavity. 
  • The binding of chemical compounds on taste receptors transmits their signal to gustatory nerve fibers.
  • The different factors contribute to the sense of taste. They are olfactive (smell), visual, sapictive (taste perception), mechanical, and trigeminal (hot or cold)
