Hemoglobin is an essential protein necessary for the transport of oxygen in the body. Biochemists study the molecular activities necessary for the exchange and transport of oxygen between the body cells and lungs.
You should compile your work for this task in a single document (e.g. Microsoft Word Google Document) that includes diagrams models text explanations and references. If a requirement asks for an explanation you should provide a written response in a narrative style (i.e. complete sentences rather than bullet points).
Note: Multimedia presentations (e.g. PowerPoint Keynote) will not be accepted due to potential originality concerns.
Note: Please save submission documents as *.doc *.docx *.rtf or *.pdf files. If you are using Google Documents you must save the file in *.pdf format and upload the *.pdf file.
Requirements:
A. Create an original model of hemoglobin with clear labels that shows how oxygen is carried by the molecule.
Note: The inclusion of the following components aids in showing how oxygen is carried: subunits heme groups iron atoms and oxygen molecules.
Note: Take a picture or screenshot of your completed model as evidence that you created it. You can include the picture or screenshot as part of your document or you can submit it in Taskstream as a separate attachment.
1. Explaintwodifferences between the oxygenated and deoxygenated states of hemoglobin.
2. Explain how pH impacts the bindingandrelease of oxygen by hemoglobin.
a. Create an original graph that demonstrates the relationship between hemoglobins oxygen binding and oxygen concentration at different pH levels.
3. Create an original diagram or series of diagrams with clear labels that compares the biochemical (protein) structure of hemoglobin to myoglobin.
Note: The inclusion of the following components aids in showing the comparison: subunits heme groups and iron atoms.
Note: Take a picture or screenshot of your completed diagram as evidence that you created it. You can include the picture or screenshot as part of your document or you can submit it in Taskstream as a separate attachment.
B. Demonstrate your understanding of sickle cell anemia by doing the following:
1. Create an original diagram that demonstrates the amino acid difference between normal and sickle forms of hemoglobin.
Note: Take a picture or screenshot of your completed diagram. You can include the picture or screenshot as part of your document or you can submit it in Taskstream as a separate attachment.
2. Create an original diagram that demonstrates the difference between normal and sickle red blood cells at the cellular level.
Note: Take a picture or screenshot of your completed diagram. You can include the picture or screenshot as part of your document or you can submit it in Taskstream as a separate attachment.
3. Explain how diseased cells differ from normal red blood cells in their capacity to transport oxygen.
4. Explain the molecular inheritance of sickle cell anemia by doing the following:
a. Identify the type of inheritance seen in sickle cell anemia.
b. Create an original diagram (e.g. pedigree charts Punnett squares) or series of simple diagrams that demonstrates how sickle cell genes are inherited.
Note: Take a picture or screenshot of your completed diagram. You can include the picture or screenshot as part of your document or you can submit it in Taskstream as a separate attachment.
C. When you use sources include all in-text citations and references in APA format.
