When molecules diffuse across a cel membrane with the help of a transport protein, it is

• facilitated diffusion
• active transport
• osmosis
• simple diffusion

Equilibrium

• When molecules are evenly spread out

• the substance that is dissolved in a solution.

• the substance in which the solute dissolves; usually water

• a mixture that forms when one substance dissolves into another

concentration gradient

• the difference in the concentration of a substance from one location to another.

• requires NO energy because molecules move from a high concentration to a low concentration

• A protein that allows large or charged molecules to diffuse across a cell membrane

• a protein that helps molecules diffuse across the membrane by carrying it across.
