Diffusion Flashcards
1
Q
What is Diffusion?
A
A process which substances can enter and leave cells.
Where particles move from an area of high concentration to an area of low concentration.
2
Q
What do we want diffuse into cells?
A
Oxygen.
3
Q
What do we want to diffuse out of cells?
A
Carbon Dioxide.
4
Q
What factors affect diffusion?
A
Concentration Gradient, Membrane Surface Area and Temperature.
5
Q
What is Concentration Gradient?
A
Something that is linked to the difference in concentration between two areas which speeds up the rate of diffusion.
6
Q
What is Membrane Surface Area?
A
Something that is linked to the difference in concentration between two areas which speeds up the rate of diffusion.
7
Q
How does Temperature affect the rate of diffusion?
A
The higher the temperature, the faster rate of diffusion.
