Questions and Answers
What is the process of diffusion of water called?
What is diffusion?
Movement of substances from areas of high concentration to areas of low concentration.
Define facilitated diffusion.
Diffusion of molecules through the cell membrane using transport proteins.
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.
