Transportation

Question 1

passive transport

Answer 1

molecules move from high to low concentration with no energy

Question 2

diffusion

Answer 2

the process by which particles move from an area of high concentration to low concentration

Question 3

equillibrium

Answer 3

equal number of particles on each side

Question 4

facilitated diffusion

Answer 4

when molecules can not directly diffuse across the membrane pass through protein channels

Question 5

aquaporin

Answer 5

pores that are water

Question 6

osmosis

Answer 6

(facilitated diffusion) is the diffusion that is of water through a selectively permeable membrane

Question 7

isotonic

Answer 7

when the concentration is the same on both sides of the membrane

Question 8

hypotonic

Answer 8

below strength

if put cell in hypotonic solution, becomes big, fat, round

Question 9

hypertonic

Answer 9

water leaves cell and the cell shrinks and becomes small

above strength

Question 10

osmotic pressure

Answer 10

the net movement of water out or into a cell exerts a force

Question 11

active transport

Answer 11

particles move from low to high concentration with energy

transport proteins are protein pumps that are found in the membrane

Question 12

endosytosis

Answer 12

the membrane forms a pocket around a particle

the pocket then breaks loose from the cell membrane

Question 13

exocytosis

Answer 13

the membrane of a vesicle surrounds the material then fuses with the cell membrane
