HOMESTASIS
Active transport
Low to high
against gradient
Uses atp
Protein pumps
moves molecules with a protein channel from low to high
Endocytosis
movement of the cell membrane to bring molecules inside
Exocytosis
movement of the membrane to make molecules exit the cell
Passive transport
High to low
Diffuse
movement of molecules from high to low
NO ATP
facilitated diffusuion
movement of molecules from high to low with protein channels
osmosis
movement of water across a membrane
Tonicity
Hypo tonic
less solute outside cell with grow/burt
Isontonic
same amount of solute inside plus outside cell stays the same
Hypertonic
more solute outside
