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...
