When a molecule other than water moves from an area of high concentration to an area of low concentration with the use of a protein it is an example of what type of
passive transport.

Osmosis

Explanation:

Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.

This direction is from high concentration to low concentration, this will create equilibrium.
