Which of the following statements best describes the relationship between the molecular mass and the permeability coefficient of the drugs, as shown in Experiment 3?
F. As the molecular mass decreases, the permeability coefficient increases.
G. As the molecular mass increases, the permeability coefficient increases.
H. As the molecular mass decreases, the permeability coefficient remains constant.
J. As the molecular mass increases, the permeability coefficient remains constant.

Experiment 3
Permeability coefficients measure a drug’s ability to break through the cell membrane of a bacterium. The larger the permeability coefficient, the faster the drug is able to transfer through the membrane. The molecular mass, in atomic mass units (amu), and permeability coefficient, in centimeters per second (cm/s) of the 5 drugs at 37◦C were measured. The results are shown in Table 3.
