Phospholipid Bilayer• Phospholipids
• Head – Hydrophilic• Tail – Hydrophobic• Tails Together and Heads Outward
• What does it allow through without energy?• Water, Oxygen, and Carbon Dioxide
• Diffusion• High to Low

Transmembrane Proteins & Selective Permeability
• Large and/or charged particles• Glucose• Sodium ions (charged)
• Gates and channels• Electrical charges
