| 11. | Such potential differences actually do occur from differences in acidity on biological membranes.
|
| 12. | "' Membrane proteins "'are proteins that interact with, or are part of, biological membranes.
|
| 13. | :Any biological membrane has many charges that part of the molecules of the membrane.
|
| 14. | Lipid bilayers of biological membranes, however, are barriers for ions.
|
| 15. | They are attractive to use as they resemble biological membranes.
|
| 16. | Liposomes can be prepared by disrupting biological membranes ( such as by sonication ).
|
| 17. | Ionophores have been used to modify the permeability of biological membranes toward certain ions.
|
| 18. | The thickness of biological membrane is approximately same with the hydrophobic core of lipid bilayer.
|
| 19. | The fluid property of functional biological membranes had been determined through x-ray diffraction, and calorimetry.
|
| 20. | ABC transporters belong to the ATP to translocate a variety of compounds across biological membranes.
