Question

Which of the following taste is mediated by inotropic glutamate receptor?

• A. Sweet
• B. Bitter
• C. Umami
• D. None of the above

Answer 1

The correct option is C Umami

• Ionotropic glutamate receptors are ligand-gated ion channels that are activated by the neurotransmitter glutamate.
• Umami describes foods with an inherent savoriness(delicious, tasty). It has been described as brothy or meaty. You can taste umami in foods like Parmesan cheese, seaweed, miso, and mushrooms, which contain a high level of the amino acid, glutamate.
  
• As the umami food contains a high level of amino acid glutamate its mediated by ionotropic glutamate receptor. The receptor detects glutamate in the food and sends signals to the brain.
• So, the correct answer is 'Umami'.
