1. Chemical Bonding In Sports Benjamin Freer

2. What Is Hemoglobin? Hemoglobin is a protein that is carried by red blood cells. It delivers oxygen gathered on the lungs to tissue throughout the body.

3. How is hemoglobin important in the transport of oxygen in our bodies? Hemoglobin is a protein that carries oxygen throughout our bodies. Alpha and Beta are the two parts of hemoglobin that must be present in order for it to work.

4. Why is the transport of oxygen by hemoglobin a real-life example of chemical bonding? Without the chemical bond of Alpha and Beta, oxygen would not be carried throughout the body. bond

5. How is hemoglobin related to a successful climb to the top of Mt. Everest? Since there is less oxygen at the summit of Everest, it is harder for hemoglobin to attach itself to oxygen to carry through the body. That is why oxygen tanks are brought along during the hike.

6. What does pH have to do with the transport of oxygen by hemoglobin? If the blood’s pH is not within 7.35 to 7.45, hemoglobin will not properly work by distributing oxygen around the body.

7. What is blood doping? Blood doping works by increasing red blood cell mass and thereby delivering more oxygen to muscle.

8. Difference between autologous and homologous blood doping In a homologous transfusion, red blood cells from a compatible donor are gathered, concentrated and then transfused into the athlete’s circulation before competitions. In an autologous transfusion, the athlete's own red blood cells are harvested well before the competition and then re-introduced before the event.

9. What is EPO and why is it used? EPO otherwise known as erythropoietin is a naturally occurring hormone growth factor that encourages the reproduction of red blood cells. It is used to treat different disorders

10. Medical uses of blood doping Given to someone who has a low amount of red blood cells. Someone who has little muscle to help them perform daily activities.

11. Blood doping used in sports Blood doping is used in sports to become number one. People ignore the side effects because they don’t look into the future.

12. Documented example: Mark McGwire Mark McGwireFormer A's and Cardinals first baseman. played from 1987-2001 and hit 583 home runs, including a then-record 70 in 1998. Accused by Canseco of using steroids. Denied use at first, then confessed in 2010 about his use of steroids, then HGH in 1989.

13. Documented example:Barry Bonds is a Major League Baseball player who played for the Pittsburgh Pirates and San Francisco Giants. Achieved all-time Major League Baseball home run record with 762 home runs. Bonds lied about his alleged use of steroids.

14. Side effects of blood doping Injecting blood doping chemicals can cause kidney damage, jaundice and blood clots.
