What is Hemoglobin?

Hemoglobin is a type of protein in the red blood cells that carries oxygen to the tissues of the body.

It’s a cell that transports oxygen and carbon dioxide and gives blood its red color.

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

It is a real-life example of chemical bonding because the hemoglobin combines with the oxygen, and when two substances combine together, it forms a chemical bond. www.investors.affymax.com/glossary.cfm

How is the Hemoglobin related to the successful climb to the top of Mt. Everest

When you climb up the Mt. Everest, you lose oxygen as you get higher so you will need hemoglobin because hemoglobin transfers oxygen to your lungs

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

The ph keeps hemoglobin in our body under control.

What is the difference between autologous and homologous blood doping?

• Autologous blood doping is the transfusion of one’s own blood, which has been stored refrigerated or frozen until needed.

• Homologous blood doping is the transfusion of blood that has been taken from another person with the same blood

What is EPO and why is it used?

• EPO is a hormone that is produced naturally by the human body. EPO is released from the kidneys and acts on the bone marrow to stimulate red blood cell production.

• An increase in red blood cells improves the amount of oxygen that the blood can carry to the body’s muscles. It may also increase the body’s capacity to buffer lactic acid.

1st example of blood doping

In 1996 the first doped athlete was Irish swimmer Michelle Smith, she won three gold medals in the Olympics, but people said that blood was transfered into her body.

2nd example of blood doping

Barry bonds was also guilty of using blood doping. He was positive of three types of steroids.
