Hemoglobin (Hb) is responsible for hanging on to oxygen

Hemoglobin (Hb) is responsible for hanging on to oxygen in your blood as Hb(O2)4. CO poisoning works by competing for the same binding site that oxygen would normally occupy as in the equilibrium below:Hb(O2)4 4CO -> Hb(CO)4 4O2Based on your understanding of LeChatelier’s principle how could you reverse CO poisoning?A) Remove HbB) Increase O2 pressureC) Decrease O2 pressure
