Chemistry: Challenges and Solutions

Hemoglobin (animation)

In our lungs, where the concentration of oxygen is high, hemoglobin bonds with oxygen to form oxyhemoglobin. Oxyhemoglobin then travels to different parts of the body where there is very little oxygen. This causes the reaction to favor the reverse direction, releasing oxygen to the surrounding tissue and recreating the hemoglobin.
