How are diffusion and facilitated diffusion diffrent?

Diffusion: Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of lower concentration. The time dependence of the statistical...

Substances enter a cell through the cell membrane

The difference between diffusion and facilitated diffusion is that facilitated diffusion is that the molecules pass through special protein channels.

As an example water molecules use a diffusive method to cross the cell membrane called osmosis, but there are channels across the cell membrane that facilitate the water passage. These are called...
