Passive Transport

Question 1

Passive Transport

Answer 1

Cell spends no energy of adenosine triphosphate (ATP) to move molecules
Molecules move from a high to low concentration
Down their concentration gradient

Question 2

Types

Answer 2

Diffusion
Osmosis
Facilitated diffusion

Question 3

Diffusion

Answer 3

Movement of molecules from an area of high to low concentration without the expenditure of energy (ATP)
Movement continues until equilibrium is reached

Question 4

Equilibrium

Answer 4

even balance of molecules
This is how many molecules move into and out of cells

Question 5

Osmosis

Answer 5

Diffusion of water through a selectively permeable membrane from a less concentrated solution to a higher concentrated solution
Distilled water
100% pure H2O (no solutes)
Hypotonic environment
Salt water
High solutes (namely salt)
Hypertonic environment

Question 6

Facilitated Diffusion

Answer 6

Facilitate means “to help”
Larger molecules enter/exit with the help of protein channels in the plasma membrane
No energy of adenosine triphosphate (ATP) used
