Facilitated diffusion is a passive transport process that allows substances to cross membranes with the help of specific transport proteins. Unlike simple diffusion, which occurs directly through the lipid bilayer, facilitated diffusion utilizes carrier or channel proteins to assist molecules that cannot easily pass through the cell membrane due to their size or polarity. This process is essential for maintaining cellular homeostasis and transporting vital substances into and out of cells.
