However, the existence of a permeability barrier means that organisms were able to evolve detoxification systems that exploit the hydrophobicity common to membrane-permeable xenobiotics.
Porén, a existencia dunha barreira de permeabilidade significa que os organismos teñen a capacidade de facer evolucionar sistemas de detoxificación que explotan a hidrofobicidade común a xenobióticos permeables á membrana.
