WebCorrect option is A) When the affinity of O 2 and CO 2 is compared, it is more for CO 2. Hemoglobin carry carbon dioxide in the form of carbamino haemoglobin (25%approx.). … 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.

WebJul 9, 2015 · It has a greater affinity for hemoglobin than oxygen does. It displaces oxygen and quickly binds, so very little oxygen is transported through the body cells. There are two equilibrium reactions of binding oxygen and becoming oxygenated hemoglobin: H b ( a q) + 4 O X 2 ( g) H b ( O X 2) X 4 ( a q)
WebThe affinity of carbon monoxide for hemoglobin is 240 times that of oxygen. 11 Once one molecule of carbon monoxide binds to hemoglobin, it shifts the hemoglobin-oxygen dissociation curve to the left, further increasing its affinity and severely impairing release of oxygen to the tissues. 11, 15 Carbon monoxide has been termed the silent killer ...

WebJan 14, 2024 · Humans elicit a robust series of physiological responses to maintain adequate oxygen delivery during hypoxia, including a transient reduction in hemoglobin-oxygen (Hb-O2) affinity. However, high Hb-O2 affinity has been identified as a beneficial adaptation in several species that have been exposed to high altitude for generations. … WebThe correct option is B b) Carbon Monoxide. Hemoglobin in humans has a very high affinity for carbon monoxide, forming carboxy hemoglobin which is a very bright red in color. Carbon monoxide is thus problematic for humans because it has affinity higher than that of oxygen. Suggest Corrections.
