Study Notes
Types of Passive Transport
-
Osmosis
- Refers to the specific diffusion process of water.
- Essential for maintaining cellular homeostasis and regulating fluid balance.
-
Diffusion
- Involves the movement of substances from regions of higher concentration to lower concentration.
- Fundamental process for substances like gases (e.g., oxygen and carbon dioxide) to cross cell membranes.
-
Facilitated Diffusion
- Involves the transport of molecules across the cell membrane with the assistance of transport proteins.
- Crucial for the movement of larger or polar molecules that cannot directly pass through the lipid bilayer.
