in hemoglobin has a higher affi nity, roughly 200 250 times greater, for CO as compared to oxygen. Given its high affi nity, CO out-competes oxygen for hemoglobin binding and can displace oxygen from hemoglobin. Additionally, binding of CO to hemoglobin changes the structure of that molecule toward the relaxed state, making it more diffi cult
