Diffusion is a process leading to equalization of substance concentrations in a system or establishing in a system an equilibrium concentration distribution that results from random migration of the system's elements. Three types of diffusion are distinguished, viz., molecular, Brownian, and turbulent.
Diffusion refers to the net movement of molecules from higher to lower concentration. Diffusion may be a simple diffusion or . A simple diffusion is one in which that occurs unassisted. Facilitated diffusion in contrast is an assisted diffusion in a way that it requires a carrier molecule. For instance, polar molecules diffuse across a cell membrane through carrier molecules in the cell membrane.
