Which abnormal hemoglobin contains a molecule of carbon monoxide?
A) Carboxyhemoglobin
B) Methemoglobin
C) Sulfhemoglobin
D) Deoxyhemoglobin

Question

Quizplus · Accepted Answer

Carboxyhemoglobin is formed when carbon monoxide binds to hemoglobin in red blood cells, leading to reduced oxygen transport capacity and potentially causing carbon monoxide poisoning. Methemoglobin is an abnormal form of hemoglobin in which the iron in heme is in the oxidized state, resulting in decreased oxygen binding ability. Sulfhemoglobin forms when a sulfur atom is incorporated into the heme group, also leading to decreased oxygen binding ability. Deoxyhemoglobin is the normal form of hemoglobin that lacks oxygen binding to the heme group.
