Study Notes
Passive Transport
- Passive transport is a type of transport that does not require energy for the movement of molecules.
Channels of Passive Transport
- There are three channels through which passive transport can happen.
Simple Diffusion
- Small, uncharged molecules can freely diffuse across a cell membrane through simple diffusion.
- Simple diffusion does not require the assistance of a transport protein.
Characteristics of Passive Transport
- The primary driving force for the movement of substances during passive transport is their concentration gradient.
- During passive transport, substances move down their concentration gradient.
- Osmosis is a type of passive transport.
- Facilitated diffusion can assist the diffusion of larger or charged molecules across a membrane.
