Question 6
How does the membrane structure provide
for cell compartmentalization and communication; what specializations can be
found in membranes for communication and other functions? [Chapter 7 and 8]
1. Read through chapter 7 and make a list of ways in which the
cell is compartmentalized by membranes and organelles.
2. What is the evidence that cell signaling evolved early in
the history of life?
3. List and define the three stages of cell signaling.
4. Most signal receptors are plasma membrane proteins, how do
these work?
5. What are signal-transduction pathways?
6. How do cells respond to signals?
7. Study the formation and use of cyclic amp ON PAGES 207-209.
8. Describe how the following are used by cells for attachment
and/or communication: Plasmodesmatas, Desmosomes, and Gap Junctions.
