This activity is intended to allow you to think about what you have learned and how you can apply it to problems or situations in the real world. To prepare for this activity log on to evolve ebook and navigate to “A & P Connects” for Chapter 3, 4 & 5.
NOW: answer the following questions and briefly describe your thoughts on the answer and how you come to that answer.
How would you design a cell membrane that would allow you to move more material through the membrane faster without taking more space?
Desmosomes, gap junctions, and tight junctions connect cells to one another. What examples can you find in your external environment of analogous structures that fit each cell connection type?
Would an intravenous injection of a 0.85% NaCl solution give the same osmotic pressure to the cells of the bloodstream as a 0.85% dextrose (glucose) solution? Is the osmotic pressure of 0.85% NaCl and 5% dextrose the same?

Task One
To allow more material to move through the membrane faster while taking a less space, I would make sure that I inverse the number of the transmembrane proteins that are located in the membrane. It is because the cell membrane is a semi-permeable membrane that allows materials to diffuse through it selectively CITATION Pat \l 1033 (Patton & Douglas). As such the materials will be transported to the various sections through the proteins that are embedded in the membrane at a faster rate than usual.
Task Two
There are analogous structures that fit each of the cell connections above. The gap junctions are analogous to the plasmodesmata that join the cells of a plant. The plasmodesmata transverse the cell wall of a plant thus allowing transport and communication. The desmosomes are analogous with the hemidesmosomes (HD) that are located in the epidermis of the skin CITATION Pat \l 1033 (Patton & Douglas). The difference is that while the hemidesmosomes attach a cell to the extrac...
