Sickle cell anemia is a disease that predominantly affects red blood cells. Red blood cells are
similar to other cells, consistent with cell theory. Which of the following is not true of all cells?
All cells within the same organism contain the same amount of proteins, membranes and
sugars.
Hemoglobin "carries" oxygen when oxygen binds to iron atoms that are embedded in
hemoglobin. How many covalent bonds can oxygen form? In other words, what is the valence of
oxygen? 2
Oxygen is "carried" by hemoglobin when the oxygen binds to an iron that sits inside a large
chemical group, known as porphyrin (shown below). This chemical group contains many
functional groups that allow it to bind within the hemoglobin protein. Which of the following
functional groups of the porphyrin ring is shown inside the red box? methyl

molecule is this: Nucleic Acid
Ultimately the first error causes an error in a molecule that looks like this. What kind of molecule
is this: Protein

Solutions
Primary Structure A chain of amino acids held together by covalent bonds
secondary structure A structure formed by hydrogen bonds between backbone atoms (not
side-chains!)
Tertiary Non-covalent interactions between the side-chains of amino acids within the
same primary structure
Quaternary Non-covalent interactions between the side-chains of amino acids in different
primary structures
Secondary structures protect __<1>__ atoms found in the __<2>__ part of the protein, when they
are folded into spaces that are more __<3>__. 1. Hydrophilic / polar
2. Backbone
3. Hydrophobic / non-polar
