5. Hemoglobin carries O2 from the lungs to tissue cells, where the O2 is released. The protein is represented as Hb in its unoxygenated form and as Hb-O2 in its oxygenated form. One reason CO is toxic is that it competes with O2 in binding to Hb: Hb-O2(aq) + CO(g) Hь-CО (аq) + O-(g) (a) If AG© z -14 kJ/mol at 37°C (body temperature), what is the ratio of [Hb-CO] to [Hb-O2] at 37°C with [O2] = [CO]? (b) How is Le Châtelier's principle used to treat CO poisoning?

5. Hemoglobin carries O2 from the lungs to tissue cells, where the O2 is released. The protein is
represented as Hb in its unoxygenated form and as Hb-O2 in its oxygenated form. One reason
CO is toxic is that it competes with O2 in binding to Hb:
Hb-O2(aq) + CO(g)
Hь-СО (аq) + O2(g)
(a) If AGO x –14 kJ/mol at 37°C (body temperature), what is the ratio of [H6•CO] to [Hb•O2]
at 37°C with [O2] = [CO]?
(b) How is Le Châtelier's principle used to treat CO poisoning?
