Which of the following are functions of the cell membrane?

1

What molecule is the majority of the cell membrane made up of?

1

Which of the following are also found in the cell membrane (in addition to the answer to the previous question).

Ribosomes

Nucleic acids

Proteins

Carbohydrates

Which of the following are ways to describe a cell membrane (or alternative names for the cell membrane) ...

1

In a cup of salt water the salt would be referred to as the ...

Solute

Solvent

Neither

1

In a cup of salt water the water would be referred to as the ...

Solute

Solvent

Neither

1

Which type of membrane transport do not use energy to occur?

1

Which of the following can move through a cell membrane without a protein channel?

A small and non-polar molecule

A large and non-polar molecule

A small and polar molecule

A large and polar molecule

1

Which of the following is true if a solute has reached dynamic equilibrium between the two sides of a membrane?

The solute has stopped moving

The solute is moving across the membrane at about an equal rate

The concentration of the solute is about equal on both sides of the membrane

The membrane no longer allows the solute to move in order to maintain equilibrium

Use the next image to answer the questions that follow. Note: if there is not a protein channel drawn do not assume it is there.

1

To start, the inside of the cell is ____ for CO2.

Hypertonic

Hypotonic

Isotonic

1

Can the CO2 move on its own (without a protein channel)?

Yes

No

1

Where will the CO2 move?

All of the CO2 will move inside the cell

The CO2 will move inside the cell until it reaches dynamic equilibrium

All of the CO2 will move outside of the cell

The CO2 will move outside the cell until it reaches dynamic equilibrium

The CO2 won’t move so water will move

1

What type of membrane transport occurred?

Use the next image to answer the questions that follow. Note: if there is not a protein channel drawn do not assume it is there.

1

To start, the inside of the cell is ____ for glycogen.

Hypertonic

Hypotonic

Isotonic

1

Can the glycogen move on its own (without a protein channel)?

Yes

No

1

Is there a protein channel for glycogen?

Yes

No

1

Where will the glycogen move?

All of the glycogen will move inside the cell

The glycogen will move inside the cell until it reaches dynamic equilibrium

All of the glycogen will move outside of the cell

The glycogen will move outside the cell until it reaches dynamic equilibrium

The glycogen won’t move so water will move

What type of membrane transport occurred?

Use the next image to answer the questions that follow. Note: if there is not a protein channel drawn do not assume it is there.

1

To start, the inside of the cell is ____________ for starch.

Isotonic

1

Can the starch move on its own (without a protein channel?

Yes

No

1

Is there a protein channel for starch?

Yes

No

1

Where will the starch move?

All of the starch will move inside the cell

The starch will move inside the cell until it reaches dynamic equilibrium

All of the starch will move outside of the cell

The starch will move outside the cell until it reaches dynamic equilibrium

The starch won’t move so water will move

1

If water moves, will the cell shrink or grow?

Shrink

Grow
