Permeable Cell Membrane
12
permeability: rate of passive diffusion of molecules through the membrane
fluid mosaic model: model composed of lipid bilayer embedded with proteins
cytoskeleton: provides a scaffolding for membrane proteins to bind to
sodium potassium pump: membrane system that only allows sodium and potassium to pass
phospholipid bilayer: fatty double layer structure of membrane
potassium: ion cell membranes are most permeable to
100: The cell membrane is____ times more permeable to potassium than sodium.
Calcium: _____ regulates sodium and potassium influx or efflux.
ATP: Energy source for cell permeability.
Active: Cell membrane transport type requiring energy.
Passive: Cell Membrane transport type that does not require energy.
Osmosis: Movement of water across membranes.
Proteins: molecules that assist ions in transport across cell membranes.
