Chapter 50.4, Problem 3CC
Summary Introduction
To predict: Whether a mutation in the mice have acted in the signaling pathway that had disrupted its ability to taste bitter, umami and sweet, but not salty and sour.
Concept introduction: Animals utilize their senses (chemical) for various purpose like recognizing the territory (marked), finding mates and navigating at the time of migration and in many other things. In all the animals, for the purpose of feeding behavior, chemical senses are essential. Perceptions of taste (gustation) depends upon the chemoreceptors.

What is signal transduction? Illustrate and describe the molecular events in signal transduction pathways involving 1) G-protein-coupled receptors and 2) enzyme linked receptors.
Put the steps of the process of signal transduction in the order they occur (hint - try to decide
which signaling pathway this is before working on the order):
1. A conformational change in the signal-receptor complex activates an enzyme.
2. Protein kinases are activated.
3. A signal molecule binds to a receptor.
4. Target proteins are phosphorylated.
5. Second messenger molecules are released.

- The hypothesis for the experiment shown in the picture is that the TamC3 and TamR3 cell lines function, and grow the absence of estrogen, receptor function. Reduced reliance on estrogen, receptor signaling alters mTOR pathway activity. If this hypothesis is true, then mediators of mTOR signaling (Akt or p70S6K) should have reduced levels of phosphorylation. Where would you look to see this? Why does the data in the picture not support the hypothesis?arrow_forward2 of 16 Compound Binds to Elicits biological receptor response A Yes Yes B Yes No C No No Refer to the table above.

So there are many examples of slow and rapid signaling via coupled receptors. For an example, salivary gland secretion is rapid signaling and cell growth is slow signaling. These pathways could be twisted and used to resolve medical issues in a more natural and less damaging way. Are there any experiments that have or could be done to test out promoting rapid signaling to speed up slow processes such as cell growth in a severe wound? What experiments have or could be done to test out slowing down signaling that is fast like cells responding to their environment negatively (over-active allergies)?
