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.
