WebApr 14, 2024 · Haemoglobin shows maximum affinity with carbon monoxide as compared to coarbon dioxide and oxygen. When compared with carbon dioxide, haemoglobin has more affinity with oxygen. When haemoglobin binds with carbon monoxide, it forms carboxyhaemoglobin. Why does myoglobin have a higher affinity for oxygen than … WebHemoglobin's affinity for oxygen increases as successive molecules of oxygen bind. More molecules bind as the oxygen partial pressure increases until the maximum amount that can be bound is reached. As this limit is approached, very little additional binding occurs and the curve levels out as the hemoglobin becomes saturated with oxygen.

WebHaemoglobin is one such conjugated chromoprotein. It is composed of a simple protein called "globin" and non protein iron ( F e2+) porphyrin complex called "heme" 100 ml of blood contains about 159 of haemoglobin. Four F e2+ ions of heme can loosely bound to upto four molecules of oxygen thus enabling haemoglobin to carry oxygen. WebSo haemoglobin has maximum affinity for CO. Moreover, haemoglobin combines with carbon monoxide to form carboxyhaemoglobin. So carbon monoxide reduces oxygen …
