FUNCTION

Selectively permeable Barrier Protection

Page 3: AKA “Plasma Membrane” or “Fluid Mosaic”. Selectively permeable Barrier Protection.

MADE OF…….

Phospholipids (Bilayer) Transport & Receptor Proteins Some Carbohydrates and Cholesterol

(fluidity)

TYPES OF TRANSPORT

2 Types of Transport Active- takes energy (ATP) & Protein-(Against Concentration Gradient)

Passive- No ATP needed (Down ConcentrationGradient)

-Diffusion (facilitated as well w/ protein) - Osmosis- diffusion of water

OTHER TYPES OF ACTIVE TRANSPORT

Exocytosis- active removal of materials from cell (vesicle)

Endocytosis- active way to bring materials into cell (vesicle)

CONCENTRATION

Solvent- the liquid (H2O) Solute- the substance being

dissolved (Salt or Sugar) Hypotonic- solution is lower

concentration of solute Hypertonic-solution is higher

concentration of solute Isotonic- concentration is equal
