What does a target cell require to respond to an extracellular
signal molecule?
Choose ONE OR MORE:
appropriate intracellular signaling pathways
a receptor that recognizes the signal molecule
access to the signal molecule
the appropriate machinery to produce and secrete the signal molecule
effector molecules that alter cell behavior in response to the signal molecule
Homework Answers
Answer. 1.appropriate intracellular signaling pathways
After extracellular signal molecule attaches to the receptor of the target cell, several downstream intracellular processes occur as a response to the stimuli.
2.a receptor that recognizes the signal molecule
specific receptors are required for detection signal molecules.
3.access to the signal molecule
signal molecules need to be in the vicinity of the target cells.
5. effector molecules that alter cell behavior in response to the signal molecule
effector cells actively respond to external stimuli and bring about change in the cell to respond to the stimuli received.

Question (1 point) 1st attempt Which statement is true about cell-surface receptors? Choose one: O All extracellular signal molecules bind to a single type of receptor. O All cell-surface receptors bind to a single, unique extracellular signal molecule. O Each cell-surface receptor can bind to an endless variety of extracellular signal molecules. Some cell-surface receptors can bind to multiple signal molecules. O All drugs block the activation of ion-channel-coupled receptors. 11 OF 15 QUESTIONS COMPLETED 07/15 >

Answer all questions
Following graphs, the cellular response, as measured in real time by the concentration of a certain active effector protein, is plotted over time for five cell types (A to E) that are treated with three different concentrations of a signal molecule. During the time period indicated by the horizontal gray bar. the signal molecule is present in the culture media at a concentration of 1 nM (dotted curve), 5 nM (gray curve), or 25 nM (solid curve)....

Choose one out of paracrine signalling, endocrine signalling, autocrine signalling and direct signalling and describe briefly the process by which this occurs. Pick a representative signal molecule from the pathway you have chosen and indicate its function, the type of cell in which it is made and the specific manner in which it acts as a signalling molecule, including the receptor that it binds to. (For example if you chose the endocrine signalling pathway you could consider looking at a...

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?...

1.One group of immune deficiency diseases is caused by an inability of CD8 effector T cells to kill virus-infected target cells, due to defects in cytotoxic vesicle exocytosis. Because of the inflammatory response that accompanies a normal virus infection, together with the prolongation of this response due to the inability to control the infection, patients with these disorders suffer from tissue damage caused by the infiltration of effector CD8 cells and activated macrophages into multiple organs. In addition, a subset...

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....
