3 factors that affect the rate of diffusion
temperature, concentration gradient, thickness of exchange surface
1 of 5
Difference between simple and facilitated
Facilitated only occurs at channels on the membrane where there are carrier protein
2 of 5
How is facilitated diffusion passive
No ATP used. as they have their own inbuilt kinetic energy
3 of 5
Define diffusion
THE NET MOVEMENT OF MOLECULES/ IONS FROM REGION WHERE THEY ARE MORE HIGHLY CONCENTRATION TO ONE WHERE THEIR CONCENTRATION IS LOWER UNTIL EVENLY DISTRIBUTED
4 of 5
Why don't glucose pass through the phospholipid bilayer
Only lipid-soluble substances diffuse across easily, water-soluble substance (glucose) diffuses slowly
