Question

Explain why carbon monoxide is able to out compete oxygen gas when binding to hemoglobin in red blood cells?Note: hemoglobin contains iron ions.
By the way i just made the title/question like that to get ur attention because i really need help:(

Answer 1

Hemoglobin is a protein containing a heme group. The heme group contains an iron molecule. The iron molecule helps bind O2 and there is a conformational change that makes it more likely for the next molecule to bind. Each hemoglobin molecule can bind up to 4 O2 molecules. CO binds more avidly and takes advantage of the conformational change. The dissociation curve shifts in comparison to oxygen.
