→ Active transport requires energy (usually in the form of ATP) to move or create the passage for substances into or out of cells.
→ Endocytosis and exocytosis are examples of active transport (only one example required).
→ In contrast, passive transport does not require energy to move substances into or out of cells.
→ Diffusion and osmosis are examples of passive transport (only one example required).
