no.

Question 17

active primary transport uses

Answer 17

ATP

Question 18

secondary transport uses

Answer 18

The electrochemical gradient

hydrophobic

Question 22

The “A” in fick’s equation is

Answer 22

The area of the membrane.

Question 23

The “X” in fick’s equation is

Answer 23

Thickness of the membrane.

Question 24

The “C” in fick’s equation is

Answer 24

Concentration Gradient

Question 25

The "D" in fick's equation is

Answer 25

Diffusion Parameter

Question 26

The "R" in fick's equation is

Answer 26

The rate of diffusion

Question 27

Isomotic

Answer 27

Equal concentrations inside and outside the cell. No effect.

Question 28

Hyperosmotic

Answer 28

When there is more concentration outside a cell than inside, causing shrinkage.

Question 29

Hypoosmotic

Answer 29

When there is less concentration outside the cell than inside, causing bloating and eventually explosion of cells.

Question 30

If the area of the membrane or the concentration gradient increase, what happens to the rate of diffusion?

Answer 30

It doubles.

Question 31

If the thickness of the membrane increases, what happens to the rate of diffusion?

Answer 31

It decreases.

Answer 32

Changes shape to allow one molecule pass through.

Question 33

Antiporter

Answer 33

Two different molecules going two different ways.

Question 34

Symporter

Answer 34

Two molecules going the same direction.
