Cell/Plasma Membrane Review

What is the function of the transport in channel proteins of the cell membrane?

• Allows large molecules to pass through the cell membrane

• Allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

What is the function of the phospholipid by layer of the cell membrane?

• allows large molecules to pass through the cell membrane

• allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

Which of the following describes the cell membrane?

• Controls what enters and exits the cell

• Protects and provide structure to the cell

• Provides energy for the cell

• Transports, proteins and lipids throughout the cell

• helps the cell to move around

Which of the following describes the four parts of the cell membrane?

• Phospholipid Bilayer, transport proteins, carbohydrates, and cholesterol

• Phospholipid bilayer, transport proteins, carbohydrates, and cell wall

• Phospholipid Bilayer, starch, carbohydrates, and cholesterol

• Cellulose, transport, proteins, carbohydrates, and cholesterol

What is the function of the carbohydrates of the cell membrane?

• Allows large molecules to pass through the cell membrane.

• Allows small, non-polar molecules to pass through the cell membrane.

• Identifies the cell and allow for cell-to-cell communication.

• Stabilizes the fluidity of the cell membrane

What is the function of the cholesterol of the cell membrane?

• Allows large molecules to pass through the cell membrane

• allows small, nonpolar molecules to pass through the cell membrane

• Identifies the cell and allow for cell-to-cell communication

• Stabilizes the fluidity of the cell membrane

Identify the structure in the diagram

Which part of the phospholipid is a hydrophilic portion? (Water-loving)

• phosphate and glycerol

• fatty acid

• water

• glycogen

which part of the phospholipid is the hydrophobic portion? (Water-hating)

• glycerol

• fatty acids

• water

What is the function of the plasma membrane?

• provide rigid support and protection to the cell

• To regulate what enters and leaves the cell

• fight, bacteria and viruses that enter the cell

• Make sure each cell can move
