What is Hemoglobin? : 

What is Hemoglobin? Hemoglobin is the protein-based part of a red blood cell that’s responsible for bringing oxygen from the lungs to the rest of the body.

How is hemoglobin important in the transport of oxygen in our bodies? : 

How is hemoglobin important in the transport of oxygen in our bodies? Hemoglobin is good for the transportation of oxygen because it contains a lot of iron which oxygen molecules bind to and carry oxygen from the lungs to muscle tissue.

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

Why is the transport of oxygen by hemoglobin a real-life example of chemical bonding? It is an example of chemical bonding because iron is positively charged and oxygen is negatively charged ion so together they form a chemical bond.

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

How is hemoglobin related to a successful climb to the top of Mt. Everest? Hemoglobin is related to a successful climb to the top of Mt. Everest because Hemoglobin carries oxygen to the muscles and the higher the altitude is, the less oxygen there is. Hemoglobin increases it’s oxygen carrying capacity during times like these.

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

What does pH have to do with the transport of oxygen by hemoglobin? When hemoglobin is mixed with oxygen, it usually releases hydrogen ions that are attached to it and they become a stronger acid. The body operates optimally at a pH of 7.4.

What is blood doping? : 

What is blood doping? Blood doping is the use of artificial means to increase the amount of red blood cells there are in the bloodstream at the same time. The more red blood cells there are, the more oxygen is transported to the muscles which increases performance in athletics.

What is the difference between autologous and homologous blood doping? : 

What is the difference between autologous and homologous blood doping? Autologous is when the patient’s own blood cells are used. Patients that may be scheduled for non-emergency surgery may be autologous donors by giving their blood in advance. In a homologous transfusion red blood cells are taken from a compatible donor and transfused with the athlete’s circulation before an endurance competition.

What is EPO and why is it used? : 

What is EPO and why is it used? EPO is a protein hormone produced by the kidney that regulates the number and volume of red blood cells in our bloodstream. EPO is used to treat certain types of anemia and it also helps create more red blood cells.

What are the medical uses of blood doping? : 

What are the medical uses of blood doping? Blood doping is usually done by athletes who compete in sports that depend very highly on your level of endurance.

Two documented examples of blood doping. : 

Two documented examples of blood doping. Thomas J. Hicks who won the Olympic marathon in 1904 was injected by strychnine during the race by his trainer. Vinokourov failed his Tour de France 2003 blood doping test.

What are the side effects of blood doping? : 

What are the side effects of blood doping? Blood doping via injecting can cause Kidney damage Aching muscles Dehydration High blood pressure Blood Clots Clogged arteries and veins
