  4. Spicy

Show answer
Correct Option: C
Explanation:
  • The upper surface of the tongue has small projections called papillae, some of which bear taste buds.
  • About 50 -150 taste cells are found in a taste bud. These cells detect all 4 tastes i.e sweet, sour, salty and bitter.
  • The taste of karela is bitter because it contains a compound called lectin. Lectin reduces blood glucose concentrations by acting on peripheral tissues and suppressing appetite. Hence the taste of karela is bitter.
  • So, the correct answer is 'Bitter'.

  1. Sour

  2. Bitter

  3. Umami

  4. None of the above

Show answer
Correct Option: D
Explanation:
Specific chemicals in solution pass into the taste bud through the taste pore to come in contact with the protein receptor sites on the microvilli of the gustatory receptor cells. The latter set up nerve impulses in the sensory nerve fibres. The nerve fibres transmit the impulses to the taste centre in the brain where the sensation of taste arises. The facial nerve serves the anterior two-thirds of the tongue, the glossopharyngeal nerve serves the posterior one-third of the tongue. 
A. Sour is found on the sides of the tongue.
B. Bitter is found on the base of the tongue.
C. Umami or savory found on all region of the tongue.
So, the correct answer is 'None of the above'.
