Document Summary

Physiology is the study of normal functioning of a living organism and its components parts. Food stomach lipids, glucose, vitamins, and proteins. Movement of molecules from an area of higher concentration to an area of lower concentration due to a molecules random thermal motion. Once chemical equilibrium has been reached the diffusion stops, but the molecules continue to move. Ions cant cross the membrane easily by single diffusion because they are polar. 4-you know the owner and the guard must let you in to see the owner to get you in (lots of work/energy) Facilitated diffusion and active transport both have: specificity, competition, and saturation.
