Diffusion Flashcards
What is diffusion?
When oxygen and carbon dioxide pass through the cell membrane
Where do molecule diffuse from and where do they go?
They move from an area of HIGH concentration to an area of LOW concentration
Does this process require energy?
No
What three factors can affect the rate of diffusion?
Concentration, temperature and pressure
How can concentration affect the rate of diffusion?
The greater the difference in concentration between two areas, the faster the rate diffusion happens
How can temperature affect the rate of diffusion?
As the temperature increases, the rate of diffusion increases too
How can pressure affect the rate of diffusion?
If there is high pressure, the molecules will quickly move from the area of high pressure to low pressure
