Question
Chapter 5.3, Problem 16CC
Summary Introduction
To determine: The factors that prevent the diffusion of atmospheric oxygen into human bodies.
Introduction: Diffusion directly across the phospholipid bilayer of a plasma membrane is known as simple diffusion. The rate of simple diffusion depends on the ability of the diffusing molecule to dissolve in the lipid layer of the membrane.
