membrane function pogil 1. type 1 ions potassium (K+), sodium(Na-), calcium(Ca+), chloride(Cl-), all polar and small 2. type 2 molecules glucose, polar and large 3. type 3 molecules water and urea, polar and small 4. type 4 molecules molecular O2 and CO2, nonpolar and small 5. oxygen and glu- what are 2 substances that need to move into a cell to cose maintain homeostasis? 6. carbon dioxide and water what are 2 substances that need to move out of a cell to maintain homeostasis? 7. phospholipid 8. ion charged atom 9. sugar (glucose) 10. urea 1/3 11. carbon dioxide 12. ions start outside the cell, can't go through the membrane well because of the charges 13. glucose starts outside the cell, can't move fluidly in and out because the molecules are very large 14. urea molecules start inside the cell, move semi-fluidly because they are polar and small 15. CO2 starts inside the cell, really fluid across the membrane because nonpolar and small 16. channel proteins help large and polar molecules pass in and out of the cell 17. passive transport the movement of substances across a cell membrane without the use of energy by the cell 18. active transport the movement of materials through a cell membrane using energy (ATP) 19. facilitated diffusion when the protein assists the molecules across the membrane along the concentration gradient, from high to low (passive transport) 20. simple diffusion molecules can pass through membrane on their own (passive transport) 21. nitrogen gas type 1 ion, can't cross the membrane alone 22. hydronium type 1 ion, can't cross the membrane alone 23. sucrose 2/3 type 2 molecule, can't move fluidly through the membrane, but can move a little 24. bicarbonate type 1 ion, can't pass on it's own 25. alanine type 3, pass with help 3/3
