DAY 2 SPOT 4 GALL BLADDER

Gall bladder stores bile. Bile is not an enzyme. Bile functions to break down fat into fat droplets by emulsification.

Emulsification is the procedure that breaks down fats into fat droplets, emulsifiers such as bile can cause fat to mix with water because of its special structure of both a polar and nonpolar end. The molecules positions themselves in the fat droplets so that their nonpolar ends point inward into droplet and the polar ends point outward.
