Deck 6: Movements Through Membranes

Question 1

When conducting the eggshell membrane experiment, what is vinegar used for?

A) To remove the shell
B) To turn the albumin white
C) To solidify the yolk
D) To make the shell turn a pinkish color
E) To separate the egg shell from the rest of the egg

Answer 1

A

Question 2

In the molasses experiment, after 30 minutes, the molasses level in the stem of the thistle tube had gone up.

Answer 2

True

Question 3

A 7% solution of glucose would be considered hypertonic to human cells.

Answer 3

True

Question 4

Which of the following statements is NOT true of diffusion?

A) It is considered to be a type of passive transport.
B) It moves substances from higher to lower concentration.
C) It occurs due to random molecular motion.
D) It requires the energy of ATP.
E) It is a type of physical transport process.

Question 5

In this lab exercise, potassium permanganate was used to illustrate the process of ________.

A) facilitated diffusion
B) active transport
C) pinocytosis
D) diffusion
E) filtration

Question 6

Which of the passive transport processes requires hydrostatic pressure to transport molecules across membranes in the body?

A) Osmosis
B) Filtration
C) Facilitated diffusion
D) Pinocytosis
E) Diffusion

Question 7

In the carrot experiment to demonstrate osmosis, we would expect the string around the carrot placed in salt water to be tighter than the one placed in tap water, because both the salt and the water diffuse into the carrot.

Question 8

An example of filtration in the body is the movement of water and small solutes through the walls of capillaries.

Question 9

If a person were to hypothetically drink a very large volume of plain tap water, his/her cells would ________.

A) undergo rapid mitosis
B) crenate
C) not change
D) shrink
E) swell, and perhaps burst

Question 10

In the lab experiment on filtration, iodine potassium iodide (IKI) is used to test for the presence of glucose.

Question 11

In the filtration experiment, which substances passed through the filter paper because of their small molecular size?

A) Water, glucose, starch, and charcoal
B) Water, glucose, and starch
C) Water and glucose
D) Starch and charcoal
E) Water, starch, and charcoal

Question 12

Cells placed in a hypotonic solution will shrink.

Question 13

Which of the following transport processes requires the energy of ATP to move substances across the plasma membrane?

A) Diffusion
B) Osmosis
C) Facilitated diffusion
D) Active transport
E) Filtration

Question 14

Passive transport processes, such as diffusion, are also called physiological processes.

Question 15

Which of the following is NOT an active process by which substances cross the plasma membrane?

A) Pinocytosis
B) Filtration
C) Active transport
D) Phagocytosis
E) All of these are active processes.
