Answer 13

Stabilizes membrane

Question 14

Simple diffusion

Answer 14

Passive
High to low
Down the concentration gradient
Through phospholipid bilayer

Question 15

Facilitated diffusion

Answer 15

Through integral protein
High to low
Passive

Question 16

Diffusion

Answer 16

Against water potential

Question 17

Water potential

Answer 17

Amount if H2O molecules

Question 18

Osmosis

Answer 18

Through phospholipid bilayer
High to low
Passive
Used by H2O molecules
Down water potential

Question 19

Active transport

Answer 19

Against gradient

Uses pump

Question 20

Bulk transport

Answer 20

Involves the cell making membrane bound vesicles to bring materials in and out of the cell

Question 21

Which molecules diffuse in diffusion?

Answer 21

Hydrophobic molecules

Small, uncharged polar molecules

Question 22

Hypertonic solution

Answer 22

The solution the cell is placed in has less water than the cell

Question 23

Hypotonic solution

Answer 23

The solution the cell is placed in has more water than the cell

Question 24

Isotonic solution

Answer 24

The solution the cell is placed in has equal amount of water as the cell

Question 25

Energy used in active transport

Answer 25

ATP (adenosine tri-phosphate)

Question 26

ATP to ADP

Answer 26

A phosphate is taken from ATP

Question 27

Sodium- potassium pump

Answer 27

Active transport; sodium and potassium atoms are pumped against the gradient using ATP helps nerve impulses by building a bigger gradient

Question 28

Bulk transport examples

Answer 28

Exocytosis | Endocytosis

Question 29

Exocytosis

Answer 29

Moving materials out of the cell; the waste/export proteins move to the Golgi apparatus where they are packaged into membrane bound vesicles. The Vesicle then merged with the cell membrane, releasing the materials

Question 30

Endocytosis types

Answer 30

Pinocytosis | Phagocytosis

Question 31

Pinocytosis

Answer 31

Small molecules/ liquids make contact with the cell membrane and the cell membrane punches off around the molecules making vacuoles (in animal cells)

Question 32

Phagocytosis

Answer 32

Large molecules make contact with the cell membrane and the membrane pinches off around the molecules. The lysosomes then fuse with the Vesicle and break down the large molecule into nutrients For example, engulfing bacteria
