According to Fick's law of diffusion, which of the following changes would decrease the rate of net diffusion of "X" across a membrane?
A)An increase in the X's concentration gradient
B)An increase in the permeability of the membrane to X
C)An increase in the surface area of the membrane
D)An increase in the thickness of the membrane
E)A decrease in the size of X

Question

Quizplus · Accepted Answer

Fick's law states that the rate of diffusion is directly proportional to the concentration gradient, permeability, and surface area of the membrane, but inversely proportional to the thickness of the membrane. Therefore, an increase in membrane thickness would decrease the rate of net diffusion of X across the membrane.
