6.3 Cell Transport

Question 1

Importance of surface area: volume ratio

Answer 1

Ensures that the exchange of resources and waste occurs quickly enough for the cell to survive

Question 2

Simple diffusion

Answer 2

Moves small, nonpolar molecules from high to low concentration without using energy or a transport protein

Question 3

Facilitated diffusion

Answer 3

Moves large, polar molecules from high to low help using a transport protein but does not use energy

Question 4

Active transport

Answer 4

Moves small molecules from low to high concentration using energy which changes the shape of the protein pump which moves the molecule through the concentration gradient

Question 5

Endocytosis and Exocytosis

Answer 5

-Endocytosis- uses vesicles to take in large molecules at the cell membrane
-Exocytosis- vesicle lipid bilayer fuses with cell membrane which releases large molecules

Question 6

Osmosis
