Passive Transport• Does not use chemical energy• No ATP is involved in this transport

Types of Passive Transport:• Diffusion • Osmosis• Facilitated transport

Active transport• This is how we move molecules from a low

concentration to a higher concentration.• To do this ATP is needed.

There are 3 types of active transport:• Carrier active transport• Endocytosis• Exocytosis

Exocytosis

Endocytosis• A vesicle formed around the substance.• Phagocytosis – large particles• Pinocytosis – small particles• Receptor-mediated endocytosis – specific

particles
