Cell Structures & Functions: HONORS

Which of the following BEST describes the structure of the plasma membrane?

• The plasma membrane is a phospholipid bilayer, with a hydrophobic interior and a hydrophilic exterior.

• The plasma membrane is a protein bilayer, with a few lipids and carbohydrates scattered throughout.

• The main component of the plasma membrane are protein channels, which control what goes in / out of the cell.

• The plasma membrane is composed of several layers of carbohydrates, which control passive and active transport.

Why are cristae important for the function of the mitochondria?

• Cristae increase the surface area for energy production.

• Cristae are critical for the structure of the mitochondria, because they support its shape.

• Cristae denature enzymes that could be harmful to the mitochondria.

• Cristae increase the surface area for photosynthesis to occur.
