DIFFUSION
PASSIVE
NO HELPER
Oxygen & Carbon dioxide
FACILITATED DIFFUSION
CARRIER PROTEINS
PASSIVE
Membrane proteins
Glucose
FACILITATED DIFFUSION
AQUAPORINS (OSMOSIS)
PASSIVE
Membrane proteins
Water
FACILITATED DIFFUSION
ION CHANNELS
PASSIVE
Membrane proteins
Ions: Na+, K+, Ca++, Cl-
ACTIVE
Membrane proteins
Moves 3 Na+ out of cells &
2 K+ into cells
ACTIVE
Membrane proteins
H+ ions
Na+ - K+ PUMP
PROTON PUMP
ENDOCYTOSIS
(phagocytosis)
ACTIVE
Vesicles
ENDOCYTOSIS
(pinocytosis)
ACTIVE
Vesicles
Exocytosis
ACTIVE
Vesicles
Large molecules/whole cells
Used by white blood cells to
destroy bacteria
Small molecules/fluids
Any substance leaving cells
Used by Golgi bodies to
export molecules
