Document Summary

Hydrophilic component nad hydrophobic component: tails are hydrophobic. Has both a polar (hydrophilic region) and a nonpolar (hydrophobic) region. Compartments: may contain different enzymes, may produce different products, may increase metabolic capacity. Permits useful nutrients to be transported into the cell. Permits harmful wastes to be transported out of the cell. Length of fatty acid tails determines fluidity (larger= less fluid) Unsaturated fatty acid because of double bond which causes it to bend: double bond: more spaced out; more fluidity. Fatty acid structure changes the permeability of membranes. Number of carbons in fatty acid tail. Cholesterol (good or bad) opens up membrane. **given situation determine if membrane is fluid or not. More space between polar heads; more hydrophobic area in the inner region. 2 ways of movement: water and solute move away from each other (outward) Solute water: water and solute move towards each other (inward) Human red blood cells placed in different solutions.
