1) A semi-permeable membrane defines a “cell” containing a 10 mM NaCl, 5 mM KCl. This “cell” is placed into a bath containing a 6 mM CaCl2 and 6 mM NaCl solution.
a) Draw a schematic of the scenario.
b) Calculate the osmotic pressure of each solution.
c) Characterize the osmolarity of the bathing solution to the cell.
d) Which of the solutes are permeants? non-permeants?
e) Characterize the tonicity of the solution to the cell.
f) Does osmosis occur? If yes, in which direction?

    4. Inspired by the natural design of cell membranes, you have invented a strange new semi-permeable membrane consisting of a water-impemeable base layer interspersed with hydrophilic transmembrane glycoproteins which form three types of channels. Channel type 'A' is approx imately 3 angstroms in diameter and lined with negative charges Channel type 'B' is approximately 3 angstroms in diameter also but lined with positive charges Channel type C is approximately 4 angstroms in diameter and electrically neutral This membrane separates two...
