What is a hemoglobin?

• A Hemoglobin is a protein-based component of red blood cells which is primarily responsible for transferring oxygen from the lungs to the rest of the body.

How is hemoglobin important in the transport of oxygen in our

bodies?

• When the hemoglobin is around a lot of oxygen it will bind the oxygen. This way hemoglobin is used by the body to take oxygen from the lungs where there is a lot of it to places like our muscles (which are low in oxygen).

Why is the transport of oxygen by hemoglobin a real-life example of chemical bonding?

• Its an example because Oxygen and the hemoglobin substance mix together to make a chemical bond, the reason for giving oxygen to the mussels when there isn't a lot usually.

How is hemoglobin related to a successful climb to the top of Mt. Everest?

• Hemoglobin helps give oxygen to your body. When going to high altitudes it is hard for your body to get the oxygen it needs. An example is running during the summer, you get less tired, in the winter you loose your breath much faster than you do in the summer because of the oxygen decline.

What does pH have to do with the transport of oxygen by hemoglobin?

• Hemoglobin is found in the red blood cells. Hemoglobin's use is to bind oxygen and those blood cells and transport them throughout the body, giving your body the oxygen it needs.

What is Blood Doping?

• The belief behind blood doping is that the extra red blood cells will deliver more oxygen and other essential elements to the athlete's muscle tissues, which means more stamina and endurance. In a competitive sport such as cycling, the difference between winning and losing can often be a matter of better conditioning, not skill or strategy.

What is the difference between analogous and homologous doping?

• analogy -- The similarity of structure between two species that are not closely related; attributable to convergent evolution.

• homology -- Similarity in characteristics resulting from shared ancestry. (More Natural)

What is EPO and why is it used?

• EPO is a protein hormone produced by the kidney. After being released into the blood stream it binds with receptors in the bone marrow, where it stimulates the production of red blood cells.

• NOTE: Additional dangers of EPO include sudden death during sleep, which has killed approximately 18 pro cyclists in the past fifteen years.

What are the medical uses of blood doping, and why are they used in sports?

• If someone is short of red blood cells blood doping can be used to save their life.

• They are used in sports because blood doping uses enhancing drugs to make the body do abnormal things, like increase red blood cell counts. Which gives the athlete more stamina to complete their activity.

Example 1 for Blood Doping

• Marion Jones “Fastest Women of Earth”• She confessed being a drug cheat and ended

her career with embarrassment and shame.

Example 2

• Marco Pantani• Committed Suicide after EPO doping

Blood Doping Side Effects• Some of the problems that can arise from an autologous blood transfusion

are phlebitis, septicemia, hyperviscosity syndrome (including intravascular clotting, heart failure and potential death), bacterial infections, and air/clot embolisms. Even more frightening is the list of diseases that can be contracted through homologous transfusions by needles. They include hepatitis, AIDS, malaria, CMV, and transfusion reactions (characterized by fever, urticaria, and possibly anaphylactic shock).
