Which of the following statements correctly explains the role of lysosomes within a cell?

• The lysosome prepares fats and lipids for transport throughout the cell by sorting and encasing them.

• The lysosome uses oxygen to convert sugar into chemical energy and also controls the metabolism of the cell.

• The lysosome breaks down molecules that are not needed within the cell and returns some of the products of digestion to the cell for later use.

• The lysosome isolates water and other molecular compounds and stores them so they can be used later by the cell, or expels them as waste products.

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.
