A facilitated diffusion does not require any energy from the cell. The cell does not supply energy in moving materials in the process of facilitated diffusion.
The cell transport materials by osmosis, active diffusion, passive diffusion and facilitated diffusion.
In facilitated diffusion, the cell transports materials using proteins which acts a binders.
Integral proteins are used to transport ions and molecules in this diffusion process and does not require energy from the cell.
