You make a phospholipid bilayer with short, unsaturated hydrocarbon tails. You measure the permeability of this membrane to oxygen and water, which are normally somewhat able to cross the membrane. You then saturate the hydrocarbon tails, and re-measure membrane permeability. You then double the length of the saturated hydrocarbon tails again, and make a third measurement of membrane permeability. You graph membrane permeability (Y) as a function of hydrocarbon tail length (X). Which of the graphs below best represents the data you expect? O Graph 1 O Graph 2 O Graph 3 y O Graph 4 y X X ^
