Two students studying physiology taste a known "bitter" substance, and both report sensing bitterness. They then sample another substance. Student A reports sensing both a bitter taste and a salty taste, but student B reports only a salty taste. What is the most logical explanation?

#Unit 7. System Physiology – Animal
  1. Student A had an allergic reaction to the food, causing him to perceive the food as being bitter.
  2. Student A has normal "bitter" taste buds; student B has defective "bitter" taste buds that result in lower sensitivity to bitterness.

  3. Student A has a protein receptor capable of detecting a bitter molecule found in that substance, whereas student B lacks that particular protein receptor.

  4. Student A has normal saliva, whereas student B's saliva is more alkaline than normal.
