One of the most important processes in biology is diffusion, the movement of particles from high concentration to low concentration. This process is passive, meaning that NO energy is used by the cell to make it happen. So, how does diffusion work? We will focus on simple diffusion across the phospholipid bilayer of a membrane, shown here ...
