Write down the definition of a macromolecule.

What is a polymer? What is a monomer?

What is so special about carbon? What does it have to do with the 4 macromolecules?

Give an example of one monomer.

How do cells use carbohydrates?

What is a disaccharide? Give a common example.

What is the difference between a monosaccharide, a disaccharide, and a polysaccharide?

What is starch? What type of carbohydrate is it?

What foods contain carbohydrates? Draw at least two examples.

Lipids (p.46-47)

What are the monomers of lipids?

Draw at least two foods/substances that are composed mostly of lipids.

Nucleic Acids (p. 47)

What are the monomers of nucleic acids?

What is the function of nucleic acids in living organisms?

What are the two basic types of nucleic acids?

What kinds of foods contain proteins?

What other element does a protein contain, besides carbon, hydrogen, and oxygen?

What are the monomers that make up proteins?

Draw the general structure of this monomer, and label the different “groups”.

What type of bonds holds these monomers together? Ionic or covalent?
