C. 716 Stonefish toxin The stonefish contains a protein toxin that forms small poresin cell membranes. When red blood cells are suspended in 150 mM sodium chloride and the toxin is added, the cells lyse. (Cells do not lyse in 150 mM sodium chloride if no toxin is added.) If the cells are suspended in a solution consisting of 150 mM sodium chloride and 30 mM of an inert polymer, the outcome depends on the molar mass of the polymer. Table C.1 summarizes the results for a series of experiments. Give plausible explanations for the following questions: a. Why do cells in 150 mM NaCl lyse when toxin is added? b. Why does toxin also lyse cells in 150 mM NaCl 30 mM polymer when the polymer molar mass is 1000, 1500, or 2000 g/mole, but not when the molar mass is 3000 or 10 000?
