requires ATP
is Water
An active transport occurs against the concentration gradient. The tendency of a substance is to diffuse from the most concentrated compartment to the least. This is why passive transport does not require ATP – it occurs spontaneously.
When a substance must be transported against its concentration gradient it requires energy to activate (active transport).
Osmosis is a type of diffusion being a passive transport. Osmosis specifically refers to water molecules diffusion.
