Diffusion
occurs when a substance moves from a region of high concentration to a region of low concentration
Facilitated diffusion
a transport protein provides a passageway for the substance to cross the membrane
Passive transport
the transport of a substance across a membrane from a region of high concentration to a region of lower concentration. does not require energy
Active transport
moves a substance from an area of low concentration to high concentration
