4.1 Quiz : Cell Membrane Structure

When a carbohydrate is attached to a phospholipid, what is the structure called?

• glycogen

• glycoprotein

• carbolipid

Which is the protein?

• A
• B
• C
• D

What does hydrophobic mean?

• Likes water as a friend
• Dissolves in water
• Loves water
• Hates water

The cell membrane is composed of a ...........

• phospholipid bilayer

• single layer of phospholipids

• carbohydrate bilayer

• single layer of carbohydrates

Identify what part of the cell membrane that is represented by letter A.

• Phospholipid Bilayer

• Integral Protein

• Cholesterol

• Carbohydrate Chain

Which of the following is NOT part of the cell membrane?

• Lipids
• Carbs
• Proteins
• Nucleic Acids

The 'membrane' pictured below would not be able to form because

• the 'heads' would repel each other

• the 'tails' would repel water on either side

• the cell membrane isn't a bilayer

• the membrane does not contain phospholipids

The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell

• Certain things can enter while others cannot

• The cell manually sorts through all materials

• Only certain cells can interact with the cell.

Which component of the cell membrane functions to help move larger materials across the membrane?

• carbohydrates
• cholesterol
• phospholipids
• proteins

What is NOT TRUE about the cell membrane

• It controls what enters and leaves the cell
• Semipermeable
• Phospholipid bilayer
• Contains digestive enzymes
