-
non-polar, hydrophobic
fatty acid tails
-
non-polar, middle portion of the cell membrane
fatty acid tails
-
embedded in the cell membrane, serve as channels & pumps
intrgral protien
-
polar portion of cell membrane oriented towards water
glycerol heads
-
provides stability for animal cell membrane
cholestral

-
diffusion of water through a selectivly permeable membrane
osmosis
-
diffusion of specific molecules through a protien channel
facilitative diffusion
-
examples of the spscific molecules who use facilitative diffusion

-
Transport that does not require energy, includes 3 types
passive transport
-
Random movement of molecules in a liquid or gas.
diffusion:)
-
specialized channels for Na and K
aquaporins
-
pumps water out of single celled organizms with no cell wall
centriole vacuole
-
Equalibrium between solute and water
isotonic
-
less solute more water, more solute on inside of cell less on outside
hypotonic
-
more solute less water, more solute on outside, less solute inside cell
hypertonic
-
provides structure, support, and protection to the cell
intregal protein
-
flexible alows cell to change shape
cholestral
-
liquid designed to be isotonic
blood-extra cellular fluid
-
not found in animal cells, but in plant, bacteria, and fungi
cell wall
-
helps maintain a chemical balance inside the cell
cell membrane
-
used to conteract turgur pressure
cell wall
-
movement of larger molecules through a protein channel
facilitative diffusion
-
shrinkage of plant cells
plasmolysis
-
requires energy in the form of ATP
Active transport
-
A sodium-potassium pump establishes.....
an electrochemical gradient
-
an electrochemical gradient is established by
cells pumping 3 sodium ions out for every 2 potassium pumped in the cell
-
what is impotant for muscle contractions and nerve impuleses
a slight negative (-) charge inside the cell relative to the outside
-
