Question

Does osmosis use ATP?

Answer 1

Osmosis:

1. The passage of water molecules across a cell's partly permeable membrane from a solution with a high concentration of water molecules to one with a lower concentration of water molecules
2. Osmosis is the process of water or solvent diffusing through a membrane that is selectively permeable from an area of lower solute concentration to a region of greater concentration until equilibrium is established.
3. Since the movement is passive and proceeds down the concentration gradient, ATP (Adenosine triphosphate) is not necessary.
