Cell Transport

Question 1

semi-permeable membrane

Answer 1

only certain molecules: small, nonpolar

Question 2

passive transport

Answer 2

no energy, goes down concentration gradient

Question 3

active transport

Answer 3

used ATP for energy + transport proteins to go against gradient

Question 4

Diffusion

Answer 4

moves down gradient ,small nonpolar molecules

Question 5

osmosis

Answer 5

water across semi-permeable membrane

Question 6

facilitated diffusion

Answer 6

PASSIVE, w/help of transport proteins

Question 7

Hypertonic

Answer 7

Higher

Question 8

Hypotonic

Answer 8

lower

Question 9

isotonic

Answer 9

equal

Question 10

sodium-potassium pump

Answer 10

maintains electrochemical gradient, 2 Na in + 3 K out

Question 11

phagocytosis

Answer 11

wrap pseudopodia around particle, creating vacuole to be digested

Question 12

pinocytosis

Answer 12

“gulps”fluid in vesicles, unspecific

Question 13

proton pump

Answer 13

transports H ions out of cell; plants, fungi, bacteria

Question 14

cotransport

Answer 14

indirectly transports other solutes

Question 15

kinetic molecular theory

Answer 15

molecules in constant motion, tendency to collide and spread out
