Verified step by step guidance

Understand the role of hemoglobin: Hemoglobin is a protein in red blood cells responsible for transporting oxygen from the lungs to the tissues and facilitating the return transport of carbon dioxide from the tissues to the lungs.

Identify the interaction between hemoglobin and carbon dioxide: When hemoglobin binds with carbon dioxide, it forms a compound known as carbaminohemoglobin. This process occurs primarily in the tissues where carbon dioxide concentration is high.

Recognize the conformational change: The binding of carbon dioxide to hemoglobin induces a conformational change in the hemoglobin molecule. This change affects its affinity for oxygen, typically decreasing it, which facilitates the release of oxygen to the tissues.

Differentiate between carbaminohemoglobin and methemoglobin: Carbaminohemoglobin is formed when carbon dioxide binds to hemoglobin. Methemoglobin, on the other hand, is a form of hemoglobin where the iron in the heme group is oxidized, and it does not bind oxygen effectively.

Conclude the process: After hemoglobin binds with carbon dioxide, it forms carbaminohemoglobin, which is crucial for transporting carbon dioxide back to the lungs for exhalation.
