1
Q
What Three Main Factors Affect The Movement of Substances?
A
Surface area to volume ratio
Temperature
Concentration gradient
2
Q
What is the rate of diffusion, osmosis and active transport higher in?
A
Cells with a large surface area to volume ratio
3
Q
What happens as particles in a substance get warmer?
A
They have more energy so they move faster
4
Q
So as temperature increases…
A
Substances move in and out of cells faster
5
Q
When do substances move in and out of cells faster?
A
There’s a big difference in conc between the inside and outside of the cell
6
Q
What does it mean if there are lots more particles on one side?
A
There are more there to move across
7
Q
What do conc gradients not affect?
A
Rate of active transport
