Ch. 7: Membrane Structure & Transport
Cell Membrane
Phospholipids
Fatty acid tails
Saturated
Unsaturated (double bonds)
Cholesterol
Selectively Permeable
Membrane Proteins
Integral Proetins
Transmembrane protein
Peripheral Protein
Selective Permeability
Transport proteins
Assist hydrophilic substances across cell membrane
Channel Proteins
Tunnel like structure that moves hydrophilic molecules + ions
Plasmodesmata
Gap Junction
Aquaporin
Carrier Protein
Binds to molecules (can cause structural change) to move across the membrane
Bulk Transport
Exocytosis
Exiting
Endocystosis
Entering
Phagocytosis
Eating/Taking in solids
Pinocytosis
Drinking/Taking in liquids
Receptor-mediated endocytosis
Regulated by receptors
Passive Transport
No ATP required
Movements of molecules from high to low concentration
Molecules are moving down its concentration gradient
Ex: diffusion, facilitated diffusion, osmosis
Active Transport
Requires ATP usage
Movement of molecules from low to high concentration
molecules moves against its concentration gradient
