The Law of________ states that particles naturally move from where they are more concentrated to where they are less concentrated

Movement of molecules down their concentration gradient (from more to less) is called

Diffusion of water molecules from more H2O to less H2O, across the plasma membrane.

Movement of molecules down their concentration gradient (from more to less) through a protein channel

In Passive Transport, particles diffuse toward_______

Equilibrium happens when molecules are evenly distributed and move back and forth across the membrane at equal rates.

Diffusion, Osmosis, and Facilitated Transport are all examples of Passive Transport because

Active Transport requires

Movement of molecules against their concentration gradient (from less to more) through a protein channel is called
