Red blood cells contain hemoglobin and transport oxygen
Methemoglobin is the type of hemoglobin that contains iron in the ferric state. This occurs when hemoglobin is unable to bind with oxygen and becomes oxidized, resulting in a form of hemoglobin that cannot effectively transport oxygen to tissues.
to transport oxygen
A protein (hemoglobin) is required to transport Oxygen around the body.
Oxygen is primarily transported into blood cells by binding to hemoglobin molecules within red blood cells. This process occurs in the lungs where oxygen diffuses from the alveoli into the bloodstream and binds to hemoglobin, forming oxyhemoglobin.
The charge of hemoglobin affects its ability to bind with oxygen. Hemoglobin carries oxygen in the blood, and the charge helps attract oxygen molecules. This process is crucial for oxygen transport in the body, as it allows hemoglobin to pick up oxygen in the lungs and deliver it to tissues throughout the body.

Hemoglobin
Nitrogen does not bind to hemoglobin in the way that oxygen does. Hemoglobin specifically binds to oxygen molecules for transport in the bloodstream. While nitrogen is present in the air we breathe, it is mostly inert and does not participate in the same biochemical interactions as oxygen with hemoglobin. Instead, nitrogen is dissolved in the blood but does not play a role in oxygen transport or exchange.
