Question

Is osmosis facilitated diffusion?

Answer 1

Facilitated diffusion:

1. Facilitated diffusion is the process of spontaneous passive transport of molecules across a biological membrane via specific transmembrane integral proteins.
2. Facilitated diffusion is the passive movement of molecules along the concentration gradient.
3. It is a selective process, i.e., the membrane allows only selective molecules and ions to pass through it.
4. It prevents other molecules from passing through the membrane.

Osmosis:

1. Osmosis is the movement of water molecules across a semi-permeable membrane from a region of high concentration of solution to a region of low concentration of the solution.
2. Osmosis and facilitated diffusion are two different kinds of passive transport.
3. Osmosis is a passive process and happens without any expenditure of energy.
