2.1.1 Diffusion Flashcards
1
Q
Diffusion
A
Overall movement of particles from a region of high concentration to low concentration
2
Q
What do particles do
A
Move down a concentration gradient until concentration of particles is same everywhere
3
Q
Energy?
A
Energy is NOT transferred during diffusion, it is a passive process
Ordinary motion of particles
4
Q
Where in body
A
Blood transports glucose+oxygen around the body which then diffuse into necessary cells for respiration
5
Q
Factors affecting diffusion
A
- shorter distance, greater rate
- steeper concentration gradient, greater net movement
- more surface area, more space
6
Q
Concentration gradient
A
Difference between concentration of 2 areas
