cell transportation

Question 1

permeable

Answer 1

membrane allows stubstances to pass thru

Question 2

selectiveley permiable

Answer 2

only allows selective things to come thru

Question 3

molecules cant passed thru if

Answer 3

too big, strongly charged

Question 4

passive transport

Answer 4

molecues passing thru without the use of energy

Question 5

active transport

Answer 5

energy is needed to pass thru, uses pumped

Question 6

three types of passive transport

Answer 6

diffussion
osmosis
facilitated diffusion

Question 7

diffusion

Answer 7

move from HIGH to low cocentration
molecules move down

Question 8

equilibrium

Answer 8

particles pass thru cell without added energy
particles moving back and forth

Question 9

isotonic

Answer 9

concentration on each side of the membrane is the same

Question 10

hypertonic

Answer 10

“above strength” solution has higher solute concentration than the cell

Question 11

hypotonic

Answer 11

“below strength” solution has lower solute concentration than the cell

Question 12

osmosis

Answer 12

diffusion of water
water can always go thru membrane

Question 13

facilitated diffusion

Answer 13

when protein helps molecules defuse

Question 14

ion chanel

Answer 14

transports protiens with polor pore

Question 15

type of ion channel

Answer 15

channel protien, carrier protien

Question 16

proton pump

Answer 16

protons are pumped across membrane from low to high cocentration

Question 17

sodium potassium pump

Answer 17

pumps sodium out while potassium is pumped in

Question 18

endocytosis

Answer 18

moves substances into the cell

Question 19

exocytosis

Answer 19

moves substances out of cell

Question 20

pinocytosis

Answer 20

type of endocytosis
encloses fluid to bring into cell
