Question

Can facilitated diffusion cause the movement of molecules from a low to high concentration?

Answer 1

Facilitated diffusion:

1. Facilitated diffusion is the transport in which substances diffuse through an area of higher concentration to an area of lower concentration.
2. It moves along the concentration gradient.
3. It only allows selective molecules to move and ions.
4. Example: Transport of glucose and amino acid to move from the bloodstream into the cell.
5. Facilitated diffusion only diffuses the molecule or ion from the higher concentration to the lower concentration. It is the passive movement of the molecule.
6. This process does not require ATPs.
