Kind of transport used by ions like Ca+ + , Cl - , Na+ , and K + to move across cell membranes Facilitated diffusion with Ion channels (Na+ and K + can also move by the Na+ - K + pump) Give some examples of membrane proteins that help move molecules across cell membranes Carriers, ion channels, aquaporins, pumps H+ ions move across cell membranes using __________ proton pumps Name a kind of transport that uses membrane proteins to help molecules move across membranes Facilitated diffusion with carriers, Facilitated diffusion with ion channels, Facilitated diffusion with aquaporins (osmosis) OR Na+-K+ pump; proton pump A membrane that lets certain molecules pass through and not others is called _______________ Semi permeable OR selectively permeable Name a kind of transport that uses vesicles to move substances across a membrane Pinocytosis, phagocytosis, Exocytosis, endocytosis Name the kind of transport that moves WATER across cell membranes OSMOSIS (Facilitated diffusion with aquaporins) A freshwater fish has about 1% salt in his body. Freshwater is close to 0% salt. Will water move into or out of this kind of fish? More solute molecules inside the fish’s cells than in the freshwater. (HYPOTONIC) Water will move INTO the fish Which organelle makes the ATP used to run the Na + -K+ pump? mitochondria Type of endocytosis in which cells take in small molecules or fluids pinocytosis The white circles stand for oxygen molecules. Use what you know about diffusion of molecules to predict which way the oxygen will move. From the lungs into the blood (High concentration to low concentration) The shrinking of a plant cell membrane away from the cell wall is called plasmolysis ____________________ This type of transport in which membrane proteins grab a molecule, change shape, and flip it across the membrane is called ________________ Facilitated diffusion with carrier proteins The type of transport that moves substances OUT of cells is called exocytosis ______________ The energy for active transport comes from this molecule ATP Kind of membrane protein used by H+ ions to cross membranes Proton pump Kind of membrane protein that moves Ca++ or Cl- across membranes Ion channel This diagram represents an animal cell in a ___________ solution. isotonic It will probably __________________ stay the same size Undergo cytolysis Undergo plasmolysis stay the same size This type of transport that opens like a gate and forms a “tunnel” through the membrane to let ions in and out is called a(n) ion channel ___________________ Tell if the transport is ACTIVE or PASSIVE PASSIVE Facilitated diffusion ___________________ PASSIVE Osmosis ____________________ Na + - K+ pump ____________________ ACTIVE Diffusion ____________________ PASSIVE Endocytosis _______________________ ACTIVE ACTIVE Exocytosis ________________________ PASSIVE Ion channels ________________________ ACTIVE Proton pump _______________________ This diagram represents an plant cell in a _______________ hypotonic solution.
