Biology 8.1

transport protein that provides a tube like opening in the plasma membrane through which particles can diffuse

passive transport

is used during active transport but not passive transport

energy

process by which a cell takes in material by forming a vacuole around it

endoctyosis

particle movement from an area of higher concentration to an area of lower concentration

channel proteins

process by which a cell expels wastes from a vacuole

exocytosis

a form of passive transport that uses transport proteins

facilitated diffusion

particle movement from an area of lower concentration to an area of higher concentration

active transport

transport protein that changes shape when a particle binds with it

carrier proteins
