Question

Quizplus · Accepted Answer

Carboxyhemoglobin, methemoglobin, and sulfhemoglobin are all abnormal hemoglobins that cannot transport or deliver oxygen. Carboxyhemoglobin occurs when carbon monoxide binds to hemoglobin, preventing it from binding to oxygen. Methemoglobin occurs when the iron in the hemoglobin is altered, preventing it from binding to oxygen. Sulfhemoglobin occurs when a sulfur molecule binds to hemoglobin, altering its structure and preventing it from binding to oxygen.
