This Concept Map, created with IHMC CmapTools, has information related to: chapter 7, proteins is amphipathic molecule, proteins determine the specific function, intercellular joining hook together to form gap juctions, channel proteins (use as tunnel that is hydrophilic) example of aquaporin-travel of water through channel protein, transport moves substances by changing shape, membranes made of lipids, fluidity allows lipids to move laterally, osmosis deal with water, membrane potenial ( voltage across the membrane) generates voltage that is called electrogenic pump, signal transduction relays messages, carbohydrates consist of covalently bonded proteins called glycoproteins, transport proteins moves by carrier proteins- change shape of passengers, plasma membrane functions performed by proteins enzymatic activity, passive transport moves by diffusion, lipids to move laterally consist of unsaturated (kinks, carbohydrates varies from cell to cell and acts as markers to distinguish one cell from another, transport proteins moves by channel proteins (use as tunnel that is hydrophilic), active transport indirectly drives contransport, concentration gradient from high to low, water too much hypotonic
