Quizplus · Accepted Answer

Fick's law of diffusion states that the rate of diffusion of a gas across a membrane depends on the membrane surface area, the concentration difference of the gas on the two sides of the membrane, and the width of the membrane. Additionally, the size of the gas molecule can also affect the rate of diffusion. However, the presence of membrane transport proteins is not included in Fick's law of diffusion.
