Simple Diffusion
Diffusion is the net movement of molecules from a region of high concentration to a region of low concentration
-
This directional movement along a gradient is passive and will continue until molecules become evenly dispersed (equilibrium)
The rate of diffusion can be influenced by a number of factors, including:
-
Temperature (affects kinetic energy of particles in solution)
-
Molecular size (larger particles are subjected to greater resistance within a fluid medium)
-
Steepness of gradient (rate of diffusion will be greater with a higher concentration gradient)
