No cellular energy (NO ATP)

Question 28

Active Transport requires

Answer 28

ATP

Question 29

Movement of molecules from an area of higher concentration to an area of lower concentration ; type of PASSIVE transport

Answer 29

Diffusion

Question 30

Movement of specific molecules (ex: H2O & Glucose) across cell membranes through channel proteins (they help) Type of PASSIVE transport

Answer 30

Facilitated Diffusion

Question 31

Diffusion of water through a selectively permeable membrane ; type of PASSIVE transport

Answer 31

Osmosis

Question 32

Cell brings materials INTO the cell (by engulfing it with the cell membrane); type of ACTIVE transport (REQUIRES ATP)

Answer 32

Endocytosis

Question 33

Cell move materials out of the cell (by fusion of a vesicle with the membrane); type of ACTIVE transport, requires ATP!

Answer 33

Exocytosis

Question 34

More solute OUTSIDE the cell than inside, water leaves the cell, cell shrinks. No organism likes this. (SHRIVELS UP)

Answer 34

Hypertonic Solution

Question 35

More solute INSIDE than outside, water enters the cell, cell swells. Plants love this solution as it keeps them turgid

Answer 35

Hypotonic Solution

Question 36

solute equal inside and outside the cell, water moves in and out, cell stays the same size, animal cells love this

Answer 36

Isotonic Solution
