membrane transport Flashcards
1
Q
passive transport
A
movement of molecules with their concentration gradient- high to low. Does nto use ATP.
2
Q
diffusion
A
passive, molecules moving from high to low.
3
Q
osmosis
A
water moves from high to low concentration of molecules through protein channels. pulled by osmotic pressures.
4
Q
active transport
A
moving molecules against the concentration gradient. Uses ATP.
5
Q
membrane pump system
A
protein channels choose molecules. ex: sodium/potassium pump
6
Q
vesicular/bulk transport
A
movement of large molecules
7
Q
endocytosis
A
cell membrane engulfs molecule. semi/ solids- phagocytosis. liquids- pinocytosis.
8
Q
hemolysis
A
breaking of blood cells
9
Q
crenation
A
cells shrinking
