You then expose the liposomes, in an aqueous solution, to sunlight. The interior of the liposomes turn blue. Further investigatin of the proton pump protein you find that treatment of either intact bacteria or the purified protein with the protease chymotrypsin result in cleavage of the protein at a single site near the amino terminus, which destroys its capacity to pump protons. When you treat the liposomes described above with chymotrypsin, the interior of the liposomes remains colorless. From these results create a diagram of that illustrates the orientation of the pump protein in the plasma membrane of the intact bacterium and the direction in which it pumps protons.
