2. List three structural properties that myoglobin and hemoglobin have in common. Then list at least one structural property that is unique to each.
3. Hemoglobin can exist in two states (T and R). Describe the three-dimensional structures of each state’s active site with relation to the binding (or not binding) of the ligand oxygen.

Answer 1

Where does myoglobin live in the human organism?

myoglobin lives in the muscle tissue of the vertebrates including human beings. its function is to carry the oxygen molecules to the muscle cells.

what is its role/function in that location?

its function is to carry the oxygen molecules to the muscle cells.

List three structural properties that myoglobin and hemoglobin have in common.

• both myoglobin and hemoglobin are oxygen carriers and contains heme (iron) group.
• both the secondary structures have eight alpha-helices
• a comparable number of amino acids only slight change

Then list at least one structural property that is unique to each.

hemoglobin can bind to four oxygen atoms

myoglobin attaches to one oxygen atom
