Wild type mice cannot taste aspartame nor does it activate mouse sweet receptors.Humans, however, find aspartame sweet. A transgenic mouse line is created in which a bitter receptor, T2R19, has been knocked out. Additionally, the human sweet receptor gene has been engineered to be expressed selectively in mouse T2R19 cells. If the mice were then tested for lick rate preference when given different concentrations of aspartame in their water, which behavioral responses would you expect?a. The mice would prefer the aspartame solution over water and would increase lick rate as the concentration of aspartame increased.b.The mice would prefer water over the aspartame solution and would decrease lick rate as the concentration of aspartame increased.c. The mice would show an inverted U function, preferring water over the aspartame solution at very low and very high concentrations but not at common (i.e., those used in food products) concentrations of aspartame.d. The mouse would show no difference in preference for water or the aspartame solution at any concentration of aspartame.e.The mice would show a U function, preferring the aspartame solution over water at very low and very high concentrations but not at common (i.e. those used in food products) concentrations of aspartame.

Which evidence supports labeled line coding in the taste system?a. Mice re-expressing PLCb2 in T2-expressing taste cells in a PLCb2 mutant mouse are able to respond to bitter tastes.b. No change in cranial nerve activity is observed when specific taste receptors are inactivated.c. The same behavioral responses are observed in response to all tastants when specific taste receptors are inactivated.d. Receptor proteins re-expressing are expressed broadly in taste cells and not in subsets.e. Increasing concentrations of tastants can overcome a genetic mutation that results in a deficiency of taste receptors.
