Question

What is the similarity between simple diffusion and facilitated diffusion?

Answer 1

similarities:
-both are types of passive transport
- they require no energy.
-both work along the concentration gradient which means they move from a region of higher concentration to a region of lower concentration

difference:
-simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel

Answer 2

Both simple and facilitated diffusion allow materials to pass through the membranes.
Both simple and facilitated diffusion require a concentration difference to move from higher level of concentration to its lower level of concentration.
Both simple and facilitated diffusion uses energy from its environment.
