Macromolecules (Biomolecules)
Use your book (section 2-3), your table and your notes to answer
the following questions on the back of this sheet or on a separate
sheet of paper
1) In order to be considered an organic compound, which element must be
present in the compound? List 5 other elements that are often present in
the major organic compounds that make up organisms?
2) List the four major types of Macromolecules that are necessary for life.
3) What is the name given to small molecules that make up larger molecules?
4) Listed below are the names of the four major classes of macromolecules as
well as their monomers. Match up the monomer(s) with their parent
compound: lipids, amino acids, fatty acids, carbohydrates, glycerol,
monosaccharides, proteins, nucleic acids, nucleotides.
5) How is a polysaccharide different from a monosaccharide? What do they
also have in common?
6) If you take a DNA molecule and break it down into smaller pieces that can
be reused to make another DNA molecule, what would the smaller pieces be
called?
7) What is unique about carbon that allows it to be the central atom in all
types of organic compounds?
8) If you digest a lipid (fat), what would it be broken down into? Explain.
9) List three functions of proteins.
10) Describe the structure of an amino acid and draw a picture labeling each
region (pg. 47-48 – figure 2-16). Circle the region of the amino acid that is
different from one amino acid to another. What is this region called?
11) What types of forces help a protein to keep its shape?
12) List two functions of lipids.
13) Draw the structure of a lipid, labeling the glycerol and the fatty acid
chains (see book, chapter 2, pg. 46 figure 2-14)
14) What is the difference between a saturated fatty acid and an unsaturated
one?
15) Glucose is an example of a:
