• Selenium
• Nitrogen

Which one of the following is not one of the four classes of macromolecules?

• Nucleic acids
• Proteins
• Carbonic acids
• Carbohydrates

How do living things use carbohydrates?

• For building cell organelles
• For energy
• For storage
• Along with amino acids,  for building proteins.

This is an example of a monosaccharide.

• Fructose
• Cellulose
  
• Proteins
• Starch

This is an example of a polysaccharide.
