Proteins in the plasma membrane are often the target of medicines.Discuss why you think this is the case. How would you determineexperimentally that a specific membrane protein was the target of adrug?
Dr Renko studied diffusion of tracer molecules to study paracellular diffusion across an epithelial monolayer of Caco-2 cells. The tracers were fluorescently labelled dextran molecules of different molecular weight. She is screening various drugs to determine whether they affect the cells in any way. Which drugs are most likely to change paracellular diffusion?
a.) Drugs that modify microvilli are the most likely to change paracellular diffusion
b.) Drugs that modify gap junctions are the most likely to change paracellular diffusion
c.) Drugs that modify with aquaporins are the most likely to change paracellular diffusion
d.) Drugs that modify tight junctions are the most likely to change paracellular diffusion
Which of the following statements are correct about how the complex biological matrix of the cell may affect protein folding, stability and function (select all that appy)?
A.
ATP tends to "bounce" along the surfaces of many proteins without forming a stable complex
B.
Proteins make up approximately 30% of the total volume of the cytoplasm in a typical cell
C.
Compettition between drug molecules and metabolites in the cytoplasm may cause unexpected drug side effects not seen with individual proteins in solution.
D.
Large protein complexes move faster through the cytoplasm than small metabolites.
E.
Complex intercations between proteins in the cell may significantly destabilize a protein compared to the isolated protein in water

- The biomolecular interaction between protein receptors and ligands is similar to that of en- zymes and substrates, which depends in part on the shape of the protein. The shape of a protein, in turn, depends on the presence of appropriate chemical bonds in the protein. Many common medications function by altering the interactions between protein receptors and ligands, thereby interfering with the normal response of a cell to specific signals. Which of the following best describes a mechanism by which a drug might interfere with a normal cellular response? A B A medication causes the cell to become more permeable and unable to maintain the conditions that allow a normal response. с A medication interrupts the electron transport chain in a cell and makes it unable to syn- thesize sufficient ATP.
