Diffusion Flashcards
1
Q
Diffusion?
A
The net movement of particles from an area of high concentration to low concentration, down the concentration gradient.
This is a passive process
2
Q
Factors affecting diffusion?
A
- Temperature
- Concentration difference
- Surface area:volume ratio
- Thickness of the membrane
3
Q
Fick’s Law of Diffusion equation?
A
Rate of diffusion directly proportional to
SA X conc.difference/thickness of membrane
