  1. what is the process of net diffusion of water across a membrane
    osmosis
  2. what process maintains similar overall solute concentrations between the cytosol and extracellular fluid
    osmosis
  3. what movement of water driven by osmosis
    osmotic flow
  4. what pressure is an indication of force of pure water moving into a solution with higher solute concentration
    osmotic pressue
  5. what pressure is a fluid force, and can be estimated of osmotic pressure when applied to stop osmotic flow
    hydrostatic pressure
  6. what type of osmosis is the total solute concentration in an aqueous solution
    osmolarity
  7. what type of osmosis has effect of osmotic solutions on cell volume
    tonicity
  8. what type of osmosis refers to the solute concentration of the solution
    osmolarity
  9. what type of osmosis is decryption of how the solution effects the cell
    tonicity
  10. what type of tonicity has solution that doe not cause osmotic flow across membrane
    isotonic
  11. what type of tonicity mean the same tension
    isotonic
  12. what type of tonicity causes osmotic flow into cell, e.g hemolysis (blood loosening, burst)
    hypotonic
  13. what type of tonicity causes osmotic flow out of cell, e.g crenation of RBC's (shrink)
    hypertonic
  14. what is .9% of nacl that is isotonic with blood
    normal saline
  15. what hydrophilic or large molecules are transported across cell membrane by this carrier-mediated
    carrier protein
  16. what type of transport can move >1 substance in only one direction
    cotransport
  17. what type transport can move 2 substances in opposite directions
    countertransport
  18. what is another name for a carrier
    exchange pump
  19. what type of CMT requires no ATP(=passive), movement limited by number of available carrier proteins (=can become saturated)
    facilitated diffusion
  20. what type of CMT requires ATP (=active), independent of concentration gradient, e.g ion pumps, sodium-potassium ATPase
    active transport
  21. what type of CMT transports mechanism does not require ATP, cell often need ATP to maintain homeostasis associated with transport
    secondary active transport
  22. what transport moves materials across cell membrane in small membranous sacs (sacs form at or fuse with plasma membrane)
    vesicular transport
  23. what are the two types of vesicular transport the require ATP
    endocytosis, exocytosis
  24. what VT is into cell using endosomoes
    endocytosis
  25. what VT has vesicles discharging material into ECF
    excotytosis
  26. what are the three kinds of endocytosis
    receptor-mediated endocytosis, pinocytosis, phagocytosis
  27. which endocytosis is known as the cell drinking cell
    pinocytosis
  28. which endocytosis is known as the cell eating cell
    phagocytosis
  29. which endocytosis cell has ligands bind to receptor, plasma membrane, folds around receptors bound to ligaments, coated vesicle forms, vesicle fuses with lysosome, ligands freed and entered cytosol, lysosome detach from vesicle, vesicle fuses with plasma membrane again
    receptor-mediated endocytosis
  30. which endocytosis cell has a formation of endosomes with ECF, no receptor protein involved
    pinocytosis
  31. which endocytosis cell produces phagosomes containing solids
    phagocytosis
