Textbook Question
Chapter 48, Problem 5U
Fick’s Law of Diffusion states the rate of diffusion is directly proportional to
a. the area differences between the cross section of the blood vessel and the tissue.
b. the pressure differences between the two sides of the membrane and area over which the diffusion occurs.
c. the pressure differences between the inside of the organism and the outside.
d. the temperature of the gas molecule.

b) decreasing membrane permeability
c) decreasing lipid solubility of the diffusing molecule
d) decreasing the concentration gradient of the diffusing molecule
