Passive transport is the movement of molecules across the plasma membrane down the concentration gradient without the input of energy[1], therefore the concentration determines the direction and rate of transport across the membrane.

There are two types of passive transport:

A carrier that transports only one substrate during facilitated diffusion is called a uniporter.
