    Chemical Bonding
  • 2. What is hemoglobin?
    Hemoglobin is the protein molecule in the red blood cells
    Carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs.
  • 3. How is hemoglobin important in the transport of oxygen in our bodies?
    delivers necessary substances to the body‘s cells
    Such as nutrients and oxygen
    Transports waste products away from those same cells. (for info & pic)
  • 4. How is hemoglobin related to a successful climb to the top of Mt. Everest?
    Since its mostly made of protein
    Its most important function of it is to build up, keep up, and replace your bodies tissue.
    It gives us energy.
  • 5. How does pH have to do with the transport of oxygen by hemoglobin?
    The more oxygen that is transported the lower the pH will be. (for pic)
  • 6. Blood doping
    The practice of boosting the total number of red blood cells in the bloodstream. In order to enhance athletic performance.
    Since they carry oxygen from the lungs more RBCs in the blood can progress an athlete’s aerobic capacity (VO2 max) & endurance.
  • 7. Autologous blood doping
    One type of transfusion. Usually involves the removal of 2 units (approx. 2 pints) of an athletes blood, Quite a few weeks before the competition.
    Blood is then iced up until 1-2 days prior to the event
    When it is thawed and injected back into the sportsperson. (for info. & pic)
  • 8. Erythropoietin-EBO
    A hormone that the kidney produces. In the bone marrow, red blood cells form.
    Its used to treat low RBC counts called anemia.
    ^ A healthy kidney…
  • 9. Medical uses for blood doping
    When there was an emergency and no time to decide to do a cross-match of a patients blood-type for transfusion
    When there’s no blood accessible or infectivity risk.
  • 10. Why is blood doping used in sports?
    For better performance in an athlete, the extra RBC’s would help more oxygen get to the muscles.
    Meaning the athlete will be quicker and improved then a non-blood doper.
  • 11. Example of blood doping (documented)
    Alexei Cherepanov, from Moscow was a 19-year-old hockey all star.
    He died from blood doping.
    Months before his death he was taking the illegal substnce. (for info & pic)
  • 12. Second example of B.D
    Pechstein- a German speed skating champion is banned for blood doping.
    Found guilty after taking a blood sample
    She is banned from February 9, 2009- February 8, 2011.,,4454303,00.html(for info & pic)
  • 13. What are the side affects of B.D?
    Has a lot of side affects that are unhealthy such as
    Damage to kidneys
    Jaundice which is when eyes, skin, and body fluids turn yellow.
    And blood clots
