diffusion moves from…
high (solute) to low (solute)
does diffusion use proteins
no
does diffusion use energy
no
is diffusion passive or active
passive
osmosis moves from…
high (water) to low (water)
does osmosis use proteins
YES (aquaporins - water channels)
does osmosis use energy
no
is osmosis passive or active
passive
facilitated diffusion moves from…
high to low
does facilitated diffusion use proteins
YES (channel proteins)
does facilitated diffusion use energy
no
does diffusion use vesicles
no
does osmosis use vesicles
no
does facilitated diffusion use vesicles
no
is facilitated diffusion passive or active
passive
active transport moves from…
low to high
does active transport use proteins
YES (protein pumps)
does active transport use energy
YES (ATP)
does active transport use vesicles
no
is active transport passive or active
active
Exocytosis moves from…
high to low and low to high
does Exocytosis use proteins
no
does Exocytosis use energy
yes
does Exocytosis use vesicles
yes
is Exocytosis active or passive
active
Endocytosis moves from…
high to low and low to high
does Endocytosis use energy
yes
does Endocytosis use proteins
no
does Endocytosis use vesicles
yes
is Endocytosis passive or active
active
Hypertonic
- Higher concentration of solute outside
- Water moves out of the cell
- animal: Cells could shrivel
- plant: Cells shrivel - cell membrane peels away from cell wall (plasmolysis)
Isotonic
- Equal concentration of solute in/out
- Water moves equally into/out of cell net 0 movement
- plant & animal: Cells are in equilibrium
Hypotonic
- Lower concentration of solute outside
- Water moves into the cell
- animal: Cells could burst (lyse)
- plant: Cells will not burst, vacuole will take on excess water (turgor pressure)
