Question 1 Different types of cells have different types of

Question 1.

Different types of cells have different types of integral membrane proteins. What would you expect to reside in the plasma membrane of an epithelial cell that might be absent from that of an erythrocyte? How do such differences relate to the activities of these cells?

Question 2.

In an experiment, let us say you plan to use liposomes in an attempt to deliver drugs to fat or muscle cells. Is there a method in which you might be able to construct the liposome to increase its target specificity?

Solution

1) Cells have different types of integral membrane proteins. Integral proteins involved in cell-cell adhesion and cell tocell communication. Epithelial cells form a tightly cohering sheet that requires such proteins, whereas erythroces occur in the body as singlecells. Epithelia would also be expected to have different types of transport proteins than erythrocytes whose primary transport activity is the exchange of bicarbonate and chloride ions...

2)The inability of these drugs to reach their target tissues or by the harmful effects that are caused on healthy tissues and organs. the real idyllic solution would be to create medication that targets specificity only those cells or tissues that are affected by disease . pre-existing methods of drug might be able to construct the liposome to increase its target specificity.
