b) Cellular membranes are generally found in environments that contain lots of water. Draw a
diagram of what the phospholipid bilayer of a plasma membrane would look like if it were placed
in a hydrophobic environment. (**Note that you only have to draw the phospholipid bilayer, you
don't have to draw the other major components again as you did in part a)
c) What part or parts of a cellular membrane play(s) a role in determining the fluidity of the
membrane?
8) Indicate which of the five major types of membrane protein (adhesion, enzymatic, recogniti
receptor, and transport) is most likely to be involved in each of the situations described below:
a) An oncologist wants to study the cells from a certain tumour that has been surgically remov
from a patient. However, she must first treat the tumour with a solution affects a membrane
protein on the tumour cells. Because of the effect of the solution on the membrane protein, the
tumour tissue falls apart into individual cells.
