1.) an endocrine signal which binds to intracellular receptors is likely to be________
A. nonpolar
B. large
C. an ion
2.) unlike GPCR, pathways, receptor tyrosine kinase (RTK) pathways
A. start with receptors forming a dimer
B. are capable of activating transcription factors
C. are not extracellular receptors
Homework Answers
1.) These signal are commonly known as secondary messenger. These are small and most likely ions. Example, calcium ion(Ca+2).
So the answer is an ion.
2.) The receptors are on the surface of cell. And start with formation of dimer.
This dimerization is initiated by binding of ligand. Their is process of autophosphorylation occurs in cytosol.

Hgs is a major target of the Ire1-dependent RNA decay pathway. Mutation of a particular stem-loop sequence in the Hgs mRNA abolishes its degradation during ER stress. What would you conclude from this result? the stem-loop is necessary and sufficient for degradation the stem-loop is sufficient for degradation the stem-loop is necessary but not sufficient for degradation the stem-loop is necessary for degradation Which of the following processes is most likely to be affected by lysosome localization/positioning in the cell?...

32. Study the signaling pathway illustrated below, which involves two different receptors. Assume that a protein is active only when it is activated, but not inhibited, by its upstream signaling molecules. Activation and inhibition are indicated by normal and blunt arrows, respectively. Assume that the transcription regulator can be activated by either the binding protein or the kinase that are immediately upstream of the transcription factor. Under which of the following conditions will the expression of target:gene "X" be induced?...

Question 10-12
10. During the mating process, yeast cells respond to pheromones secreted by other yeast cells. These pheromones bind GPCRs on the surface of the responding cell and lead to the activation of proteins inside the cell. When a wild-type yeast cell senses the pheromone, its physiology changes in preparation for mating: the cell stops growing until it finds a mating partner. If yeast cells do not undergo the appropriate response after sensing a pheromone, they are considered sterile....
