Chemical Bonding Power Point1

  1. 1. By: Jessica Kushner<br />Jan. 30, 2010Period’s 1 & 2<br />Chemical Bonding<br />
  2. 2. What is hemoglobin? <br />Hemoglobin is the protein molecule in the red blood cells <br />Carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs.http://www.medicinenet.com/hemoglobin/article.htm <br /> http://en.wikipedia.org/wiki/Hemoglobin<br />
  3. 3. How is hemoglobin important in the transport of oxygen in our bodies?<br />delivers necessary substances to the body‘s cells<br />Such as nutrients and oxygen <br />Transports waste products away from those same cells.<br />http://en.wikipedia.org/wiki/Blood (for info & pic)<br />
  4. 4. How is hemoglobin related to a successful climb to the top of Mt. Everest?<br />Since its mostly made of protein <br />Its most important function of it is to build up, keep up, and replace your bodies tissue. <br />It gives us energy.<br />http://www.medicinenet.com/hemoglobin/article.htm<br />http://en.wikipedia.org/wiki/Mount_Everest<br />
  5. 5. How does pH have to do with the transport of oxygen by hemoglobin? <br />The more oxygen that is transported the lower the pH will be.<br />http://people.eku.edu/ritchisong/301notes6.htm<br />http://www.chem4kids.com/files/react_acidbase.html (for pic) <br />
  6. 6. Blood doping<br />The practice of boosting the total number of red blood cells in the bloodstream. In order to enhance athletic performance. <br />Since they carry oxygen from the lungs more RBCs in the blood can progress an athlete’s aerobic capacity (VO2 max) & endurance.<br />http://www.cartoonstock.com/directory/b/blood_doping.asp<br />http://en.wikipedia.org/wiki/Blood_doping<br />
  7. 7. Autologous blood doping<br />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. <br />Blood is then iced up until 1-2 days prior to the event<br />When it is thawed and injected back into the sportsperson. <br />http://www.teachpe.com/drugs/doping.php (for info. & pic)<br />
  8. 8. Erythropoietin-EBO<br />A hormone that the kidney produces. In the bone marrow, red blood cells form.<br /> Its used to treat low RBC counts called anemia. http://www.answers.com/topic/erythropoietin<br /> http://www.3dscience.com/3D_Images/Human_Anatomy/Urinary/Kidney/index.php<br />^ A healthy kidney…<br />
  9. 9. Medical uses for blood doping<br />When there was an emergency and no time to decide to do a cross-match of a patients blood-type for transfusion<br />When there’s no blood accessible or infectivity risk.http://www.teachpe.com/drugs/doping.php<br />http://news.bbc.co.uk/sport2/hi/front_page/2965802.stm<br />
  10. 10. Why is blood doping used in sports?<br />For better performance in an athlete, the extra RBC’s would help more oxygen get to the muscles. <br />Meaning the athlete will be quicker and improved then a non-blood doper. http://www.kidzworld.com/article/1832-blood-doping-in-sports-athletes-cheating<br />http://www.kidzworld.com/article/1832-blood-doping-in-sports-athletes-cheating-website<br />
  11. 11. Example of blood doping (documented)<br />Alexei Cherepanov, from Moscow was a 19-year-old hockey all star.<br />He died from blood doping. <br />Months before his death he was taking the illegal substnce.<br />http://deadspin.com/5119755/dead-rangers-prospect-was-doping (for info & pic) <br />
  12. 12. Second example of B.D<br />Pechstein- a German speed skating champion is banned for blood doping. <br />Found guilty after taking a blood sample<br />She is banned from February 9, 2009- February 8, 2011. <br />http://www.dw-world.de/dw/article/0,,4454303,00.html(for info & pic) <br />
  13. 13. What are the side affects of B.D?<br />Has a lot of side affects that are unhealthy such as<br />Damage to kidneys<br />Jaundice which is when eyes, skin, and body fluids turn yellow. <br />And blood clots<br />http://www.kidzworld.com/article/1832-blood-doping-in-sports-athletes-cheating<br />http://yourtotalhealth.ivillage.com/blood-clots.html<br />
