Membrane Knowledge

3. __________ proteins. Catalyze chemical reactions on the membrane
5. elemental molecule that is needed to produce energy in humans and can move across a membrane directly through phospholipids
6. endocytosis of a solid including cells
10. relatively higher solute concentration across a membrane
17. particles that are dissolved in an solution
18. droopy plant cell with less than optimal water in its vacuole and cytosol
19. bulk export across a membrane after excretory vesicle fuses with the plasma membrane
21. means two layers
22. diffusion of water
23. lipid with both hydrophobic and hydrophilic regions
24. makes matter vibrate
28. compound that a waste product during cellular energy productions in humans and can move across a membrane directly through phospholipids
30. endocytosis of a solution
32. about the same solute concentrations across a membrane
33. movement up a concentration gradient across a membrane, through a protein and using energy directly
34. movement from higher concentration to lower concentration
35. common fruit with trillions of membrane phospholipids and cell walls made of cellulose
36. dissolves particles to make a solution

1. ripping away of plant cell membrane from cell wall when too much water is lost to the extracellular fluid
2. diffusion across a membrane (down a concentration gradient) with the help of a membrane protein
4. membrane proteins involved in facilitated diffusion and active transport
7. carbohydrate attached to membrane lipid and helps to identify cells
8. outside the cell
9. __________ proteins. Protein based hormones may be recognized by these proteins
11. molecule that stabilizes plasma membranes at cell temperatures in animals
12. mixes with water well
13. selectively permeable structure made of phospholipids, proteins, cholesterol (animal cells only) and carbohydrates.
14. carbohydrate attached to membrane protein and helps to identify cells
15. movement across a membrane down a concentration gradient without using energy directly
16. solute we used to make the plant cells lose water in the plasmolysis lab
20. inside the cell
25. does not mix with water well
26. difference in concentration across a membrane
27. bulk transport when a cell engulfs food or solution using the plasma membrane and forming a food vacuole.
29. relatively lower solute concentration across a membrane
31. undomesticated donkey relative that has plasma membranes but no cell walls
