Transport through Cell Membrane

Question 1

transport that does not require
the cell to expend energy

Answer 1

Passive membrane transport

Question 2

does require the
cell to expend energy, usually in the form of ATP

Answer 2

Active membrane transport

Question 3

diffusion, osmosis, and facilitated
diffusion are under what transport mechanism

Answer 3

Passive membrane transport

Question 4

active transport, secondary active transport,
endocytosis, and exocytosis are under

Answer 4

Active membrane transport

Question 5

movement from high concentration to a low
concentration

Answer 5

Diffusion

Question 6

the difference in the
concentration of a solute in a solvent between
two points divided by the distance between the
two points

Answer 6

concentration gradient

Question 7

Class of cell membrane channels that constantly allow ions to pass through.

Answer 7

Leak channels

Question 8

limit the movement of ions across the membrane by opening and closing

Answer 8

Gated channels

Question 9

the diffusion of water across a selectively permeable membrane from a region of higher water concentration to one of lower water concentration

Answer 9

Osmosis

Question 10

a process that that brings
materials into cell using vesicles

Answer 10

Endocytosis

Question 11

often used for endocytosis when
solid particles are ingested

Answer 11

Phagocytosis

Question 12

has much smaller vesicles formed,
and they contain liquid rather than solid
particles

Answer 12

Pinocytosis

Question 13

involves the use of membrane-bound
sacs called secretory vesicles that accumulate
materials for release from the cel

Answer 13

Exocytosis
