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.

Last guy got it wrong - Thank you.
2. You discover a signal transduction pathway that regulates actin polymerization. SigC is the ligand, which binds to and activates a receptor tyrosine kinase (RTK). Activation of the RTK leads to the activation of the Ras protein, which then activates the protein kinase PK1 that phosphorylates the RingA protein on S34. When SigC plasma membrane phosphorylated, RingA binds EXTRACELLULAR to the gene regulatory SPACE inactive Ras protein activated Ras protein protein, AP1....

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...

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.

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....
