Hemolysis of Horse Red Blood Cell - Essay ExampleThere atomic number 18 factors that contribute to the king of the solute to pass through the electric cell membrane. One is the permeability of the cell membrane. Cell membrane is a lipid bilayer which does not allow ions and small hydrophilic molecules to freely pass the membrane (Kimball). Thus, for the sodium chloride, sodium sulfate and D-glucose solution to hemolyze the cell, a dilute solution should be used since this would increase the water concentration in the medium causing osmosis to occur.Another factor that determine membrane permeability is lipid solubility. Generally, low solubility in lipid would mean slower appreciate of entry to the cell (Crawford). Hydrophilic substances will pass through the membrane slowly. As shown in the results, D-glucose, sodium chloride and sodium sulfate were not able to bring on hemolysis,Polarity and molecular size also affect the rate of entry of solute. Most polar molecules are hydrop hilic they cannot easily permeate the membrane (Cell Membrane, 2). Ethanol, propano-1-ol and glycerol, although polar, are small enough to pass through the membrane (Membrane Permeability). Notice that the time of hemolysis increases with molecular size with the glycerol having the longest time.Ammonium chloride was able to hemolyze the cell compared to other salts.
