Web Activity: Macromolecules in Cells

What is a macromolecule?
                       A class of large molecules that are very important biologically. May be a protein,lip nucleic acid or polysaccharide.

What is a monomer?
                      Any of several small molecular structures that may be chemically bonded together.

What is a polymer?
                       A large molecule made up of similar or identical subunits called monomers.

List the four main types of macromolecules.
                    The four main types of macromolecules are proteins,lipids, carbohydrates and nucleic acid.


In the learning materials box click the link for the activity “making and breaking polymers.”  Use this activity to help answer the following questions:

What are the types of reactions that macromolecules are shown to undergo?
                   Macromolecules form when monomers are linked together to form longer chains called polymers.
