Hi, so just a quick question which should be simple but I can't seem to find the straightforward answer to.
Are aquaporins a part of osmosis (diffusion of water across a partially permeable membrane), or are they just a part of facilitative diffusion of water?

I think aquaporins are a specific type of channel proteins which facilitate osmosis. E.g. you have some channel proteins which specifically facilitate the diffusion of sodium ions, its the same principle for aquaporins.

Osmosis- the movement of water down a water potential gradient
Facilitated diffusion- aided diffusion across a membrane
Aquaporins- protein channels which facilitate the movement of water across a membrane via osmosis

Does this make sense?

Okay so the aquaporins allow osmosis to take place by the movement of water molecules from a high to a low water potential until it reaches an equilibrium?
