10.
The diagram above illustrates the structure of glucose. Which of the following
describes how the body uses molecules like the one illustrated above?
A. Sugar from carbohydrates, which are linked together to form fats that store
energy.
B. Carbohydrates are broken down into glucose, which is stores inside the
body’s cells.
C. Sugars are broken down into proteins that become the building blocks of
the body’s tissues.
D. Carbohydrates, such as glucose, are broken down to release chemical
energy that is used by the body’s cells to make ATP.
11. Phospholipids are linear molecules with one polar end and one nonpolar end.
How does this structure relate to their function in cell membranes?
A. The polar tails of the phospholipids form the outside of the cell membrane.
B. The nonpolar heads of phospholipids form the outside of the cell
membrane.
C. The non-polar tails of phospholipids combine to form the middle of the cell
membrane, with the heads on the outside.
D. The polar heads of the phospholipids combine to form the middle of the cell
membrane, with the tails on the outside.

A. Phospholipids.
B. Fatty acids.
C. Polar molecules.
D. Saturated fats.
