Facilitated diffusion is the movement of substances from higher to lower concentration across a semipermeable membrane with the help of specific protein carriers, without requiring energy input.

The transfer of energy from molecule to molecule is called conduction. In this process, kinetic energy is passed from one molecule to another through direct contact.
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
