  1. State in which the fluid concentrations are equal on the two sides of the cell membrane?
    Osmotic Equilibrium
  2. When some solutes are more concentrated in one of the two body compartments than the other?
    Chemical Disequilibrium
  3. When the insides of cells are slightly negative relative to the extracellular fluid?
    Electrical Disequilibrium
  4. The comparison of amount of substance compared to the solute in which it is placed.
    Concentration Difference
  5. Molecules in which the concentration is higher on one side of the membrane than on the other. Also the formula for this action?
    Concentration Gradient (C1-C2)/D *C=Concentration and D=Distance
  6. State in which the concentration has equalized throughout the system but molecules continue to move?
    Dynamic Equilibrium
  7. An example of this is when the rate of diffusion increases, temperature also increases.
    Directly Proportional
  8. An example of this is the larger the molecule, the slower the diffusion rate, or the smaller the molecule, the faster the diffusion rate is.
    Inversely Proportional
  9. When a membrane selectively allows a substance to pass through it, it is said to have this?
  10. The term used when the diffusing molecule increases, membrane permeability to the molecule increases. Think phospholipids.
    Lipid Solubility
  11. The separation of smaller molecules from larger molecules or of dissolved substances from colloidal particles in a solution by selective diffusion through a semipermeable membrane.
  12. How a cell would react when placed in a solution and allowed to come to equilibrium.
  13. If the cell in the solution does not change size at equilibrium it is this?
  14. If the cell in the solution gains water and swells it said to be this?
  15. If the cell loses water and shrinks it is said to be this?
  16. When there are proteins in the plasma but these proteins are absent from interstitial fluid the pressure created is known as this?
    Colloid Osmotic Pressure
  17. Colloid Osmotic Pressure is also known as this term?
    Oncotic Pressure
  18. A process resulting from osmosis in which cells, in a hypertonic solution, undergo shrinkage and acquire a notched or scalloped surface?
  19. The destruction or dissolution of red blood cells, with subsequent release of hemoglobin?
  20. This is what is measured when a solution of higher concentration flows into an area with lower concentration?
    Osmotic Pressure
  21. The concentration of osmotically active particles per liter of solution? And it’s formula?
    Osmolarity S/V=C *S=solute in mosm, V=volume in liters, C=concentration
  22. If the solute particles can enter the molecule we call them this?
    Penetrating Solutes
  23. If the solute particles cannot cross the cell membrane we call them this?
    Nonpenetrating Solutes
