Cell Membrane & Transport Quiz Review

Which of the following is false about the cell membrane?

• It is selectively permeable.

• It is the site of protein synthesis.

• It is needed for homeostasis.

• It is a phospholipid bilayer.

Which of the following cell membrane molecule is paired correctly with its function?

• cholesterol - strengthens the membrane

• carbohydrate - passageway for materials

• cytoskeletal proteins - used to recognize other molecules

• proteins - convert carbs into energy

What is diffusion?

• uses a protein channel

• active transport

• passive movement of solutes

• passive movement of water

What is osmosis?

• uses a protein channel

• active transport

• passive movement of solutes

• passive movement of water

What is facilitated?

• uses a protein channel

• active transport

• passive movement of solutes

• passive movement of water

What kind of solution causes the cell to shrink because water moves out of the cell?

• hypertonic

• hypotonic

• isotonic

• semitonic

What is the difference in amount/number/percentage of molecules known as?

If a fish that lives in saltwater is moved into a fresh water environment, what will happen?

• Water will leave the cells causing them to shrink.

• The cells will stay the same size.

• Water will enter the cells causing them to expand.

• Solutes will diffuse into the cells.

How is active transport different from passive transport?

• Active transport does not use energy.

• Active transport goes down (with) the concentration gradient.

• Active transport goes from high to low concentration.

• Active transport goes from low to high concentration.

Ions are in low concentration outside of the cell. They move into the cell by protein molecules. What kind of transport is this?

• Active Transport

• Passive Transport

• Facilitated Diffusion

• Ionization
