Mechanisms of Transport
- A variety of processes allow for the movement of ions and other molecules across membranes
- This allows cells to regulate what goes in and out depending on their requirements
- Transport mechanisms include:
- Passive transport (covered in 2.6 Membrane transport) :
- Diffusion
- Facilitated diffusion
- Osmosis
- Active transport (covered in 2.6 Membrane transport) :
- Endocytosis and exocytosis
- Passive transport (covered in 2.6 Membrane transport) :
Exam Tip
You should be able to describe the processes (linked to above) that allow ions and other molecules to move across membranes.
Diffusion, osmosis, facilitated diffusion, active transport including endocytosis and exocytosis
