Facilitated diffusion X Analogy- rowing a boat down stream X Analogy- pushing a boulder up a hill X Na-K pump X Look at the U tube below. The two sides of the tube are separated by a selectively permeable membrane. The membrane is permeable to glucose and fructose. The membrane is impermeable to starch. Will the fructose move? Yes Will the glucose move? Yes Will the starch move? No Which way will the water move? To the right side of the U-tube What will happen to the height of the water in each side of the U tube over time? The height of the water will decrease on the left side and increase on the right side. Fill in the following chart. You may check more than one column. Diffusion Osmosis Facilitated Active Bulk diffusion transport transport ATP X X required No ATP X X X High X X X concentration to low Move against X X concentration Water X CO2 and O2 X Glucose X Uses a X X carrier protein Minerals X being stored in the roots of plants Draw and label a cross section of the cell membrane. Include the phospholipid bilayer (hydrophilic head and hydrophobic tails), carrier protein, and peripheral proteins. Be sure to include a glycoprotein (responsible for cell recognition)
