All of the following transpo processes follow 'saturation kinetics' except
Diffusion primarily depends on the concentration of molecules. Passage of ions or molecule from a region of higher concentration to a lower concentration without the expenditure of energy is called diffusion. (REF TEXTBOOK OF MEDICAL PHYSIOLOGY GEETHA N 2 EDITION, PAGE NO - 4)
Facilitated diffusion
