Explain how methemoglobin is formed and how its presence impacts oxygen delivery. Be sure to include oxygen affinity in your answer
What will be an ideal response?
Answer: Methemoglobin is formed by oxidation of ferrous iron to ferric iron in the hemoglobin molecule. As a result, it cannot effectively transport oxygen because of its poor oxygen affinity. Patients with this abnormal hemoglobin have cyanosis and shortness of breath as a result of poor oxygen transport.
