1

transport ions in and out of cells

channel protiens

2

control chemical reactions usually by speeding them up

enzyme protiens

3

the reason that transplanted organs may be rejected by the patient

identity proteins

4

important for metabolism

enzyme proteins

5

blood types are an example of these

identity proteins

6

bind with medications so that the drugs can affect the cells' function

receptor proteins

7

have to do with Na, K, Cl, Ca

channel protiens

8

provide individual uniqueness to every cell in our body

identity protiens

9

connect to substances on the cell membrane

receptor proteins

10

intracellular fluid

cystosol

11

structures inside a cell that have a unique purpose

organelles

12

movement of a substance from high to low concentration

diffusion

13

contains dissolved substances

solution

14

chemicals that are dissolved in fluids

solute

15

the liquid that something could be dissolved in

solvent

16

inside

intra

17

outside

extra

18

between

inter

19

concentration imbalance between two solutions across a membrane

gradient

20

there is no concentration difference between two fluids

isotonic

21

refers to a solution with many substances dissolved within it

hypertonic

22

refers to a solution with only a few substance dissolved within it

hypotonic

23

substances move "down hill" with the concentration gradient from high to low concentration

simple diffusion

facilitated diffusion

osmosis

24

substance are moved "up hill" against the gradient from low to high concentration

active transport

25

movement of water from a hypotonic solution to a hypertonic solution

osmosis

26

requires a "helper" to move the substance into the cell

facilitated diffusion

27

require ATP energy to move the substance

active transport

28

movement of water towards solutes across a semipermeable membrane

involves difference in water pressure on two sides of a membrane

increased pressure forces fluid out of cell or vessel

filtration

29

transport of substance in the cell inside a "bag"

vesicle transport

30

bring substance into the cell

phagocytosis

pinocytosis

endocytosis
