Active Transport • Active transport requires energy • Moves molecules from low concentration to high concentration • Requires use of special membrane proteins

Active Transport • Active transport also includes endocytosis and exocytosis • Endocytosis is when molecules are brought in to the cell through movement of the membrane • Exocytosis is when molecules are pushed out of the cell due to movement of the membrane
