Guided Notes
Key concepts students will learn:
- •
In diffusion, particles move from an area of high concentration to an area of low concentration, without using protein channels or ATP.
- •
Active transport requires energy in the form of ATP to move molecules against their concentration gradients, often using carrier proteins like the sodium-potassium pump.
- •
Endocytosis and exocytosis are forms of bulk transport that use vesicles to move large quantities of molecules across the cell membrane, requiring the cell to expend ATP.
