True about facilitated diffusion are all except:
Occur in direction of concentration gradient.
Does not require energy.
Occur in direction opposite to electrical gradient.
Facilitated by charge of molecule.

When carrier proteins move substances in the direction of their chemical or electrical gradient, no energy input is required and the process is called facilitated diffusion.
Diffusion- process in which solute particles move from a more concentrated environment to a less concentrated one in order to bring a uniform concentration throughout.
