Facilitated Diffusion

• Facilitated diffusion involves carrier proteins that bind to specific molecules and transport them across the plasma membrane without using energy.
• Facilitated diffusion involves carrier proteins that bind to specific substances and transport them across the plasma membrane without energy input.
• Facilitated diffusion involves carrier proteins that bind to specific molecules and transport them across the plasma membrane without energy input.
• Facilitated diffusion involves the roles of carrier and channel proteins.
• Cells may be adapted for rapid transport across their internal/external membranes by an increase in the surface area of, or by an increase in the number of protein channels and carriers in, their membranes
• In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
