1. Pinocytosis Cell drinking
2. Phagocytosis Cell eating
3. Exocytosis release of substances outside a cell by the fusion of a vesicle with the membrane.
4. Endocytosis process by which a cell takes material into the cell by infolding of the cell mem-
brane
5. osmosis Low to High, Diffusion of water through a selectively permeable membrane
6. Diffusion Movement of molecules from an area of higher concentration to an area of lower
concentration.
7. tonicity the ability of a surrounding solution to cause a cell to gain or lose water
8. isotonic solution when the concentration of two solutions is the same (moving in and out equally)
9. hypertonic solu- A solution in which the concentration of solutes is greater outside then inside the
tion cell that resides in the solution
10. hypotonic solu- Solute concentration is less than the inside the cell; cell gains water
tion
11. oncotic pressure pulls fluid into the capillaries and/or prevents fluid from leaving.
12. hydrostatic pres- increases filtration by pushing fluid and solute OUT of the capillaries
sure
13. crenation This happens when a cell shrinks and shrivels; can result in cell death if severe.
14. hemolysis destruction/split of red blood cells
15. active transport the movement of ions or molecules across a cell membrane into a region of higher
concentration, assisted by enzymes and requiring energy.

16. passive(facilitat- the movement of substances across a cell membrane without the use of energy
ed) transport by the cell
17. Co-transport TWO substances are transported together by one protein no ATPase activity
18. Countertrans- One substance is being transported into the cell membrane and the other is
port getting transported in the opposite direction.
19. What are some • Temperature
factors that af- • Solvent Density
fect diffusion? • Distance traveled
20. Simple Diffusion high to low concentration easy to flow through cell membrane; Oxygen is an
example
21. Channel Mediat- Only the right shape gets through example little kid shape puzzles
ed
22. List the three cat- • Active transport
egories of trans- • Carrier Mediated
port across the • Channel mediated
cell membrane.
23. the structure of outer membrane, inter membrane space, inner membrane, cristae (folds in im),
the mitochondri- matrix
on
24. phosphorylation The metabolic process of introducing a phosphate group into an organic mole-
cule.
25. Hydrolysis how the body breaks the bonds between the last two phosphates in ATP, which is
what gives us energy
