Question 2 - 20 • True or False • Active Transport does not require any energy.

Answer 2 – 20 • False

Question 2 - 30 • Molecules that are too large to enter the cell membrane the normal direction of diffusion requires what type of transport?

Answer 2 – 30 • Active Transport

Question 2 - 40 • What type of energy is needed for active transport?

Answer 2 – 40 • ATP

Question 2 - 50 • Who controls what enters and leaves the cell?

Question 4 - 10 • The process in which the cell membrane surrounds a particle and encloses it in a vesicle to bring it into the cell.

Answer 4 – 10 • endocytosis

Question 4 - 20 • The process used to remove large particles from a cell. The vesicle containing the particles fuses with the cell membrane.

Answer 5 – 10 • Be able to pump water out so it does not pop

Question 5 - 20 A solution is considered to be hypertonic when it has (more/less/equal) solute molecules than the inside of the cell.

Answer 5 – 20 More

Question 5 - 30 • A substance that moves across a cell membrane without using cell’s energy tends to move: • A) away from the area where its less concentrated • B) away from the area where it is more concentrated

Answer 5 – 30 • B) away from the area where it is more concentrated

Question 5 - 40 • Can a person survive if they drink saltwater?

Answer 5 – 40 • No because your cells will lose water and you will get dehydrated.
