Facilitated Diffusion in Cellular Biology
Passive transport constitutes the cellular mechanism of solute and solvent movement across biological membranes that occurs without the direct expenditure of metabolic energy. This theory distinguishes between simple diffusion, facilitated diffusion requiring transmembrane protein channels, and osmosis, the specific diffusion of water driven by concentration gradients. Operating within the domain of cellular biology and biophysics, these processes define the fundamental physical rules maintaining cellular homeostasis and material exchange.
