4. (6 pts) Hemoglobin (Hb) binds to both oxygen and carbon monoxide. When the carbon monoxide replaces the oxygen in an organism, the following reaction occurs: HbO2 + CO → HbCO + O2) At 37°C. K is about 200. When equal concentrations of HbO2 and HbCO are present, the effect of CO inhalation is fatal. Assuming Poe = 0.21 atm, what is Poo when [HBO3) - [HbCO)?
The binding of oxygen to hemoglobin in the blood involves the equilibrium reaction: Carbon monoxide replaces oxygen in oxygenated hemoglobin according to the reaction: HbO2(aq) + CO(aq)HbCO(aq) + O2(aq) a. If the normal pH of blood is controlled within a range of 7.35 to 7.45. If the pKw is 13.63, what is the normal range of [H+] and [OH- b. What would happen if oxygenated hemoglobin became too acidic? c. Use the reaction and associated equilibrium constants at body temperature...
1. Carbon monoxide poisoning can happen because carbon monoxide has a higher affinity for hemoglobin than oxygen does. This can be seen by comparing the equilibrium constants for the two reactions Hb(a)+02()Hb02(aq) Hb(a)C(e) HbCO(aq) K 1.9x1012 K 1.1x1014 where Hb is hemoglobin. The actual reactions are more complicated since each hemoglobin can accept up to four oxygen molecules, but we will simplify it for this problem A concentration of about 12,500 parts per million of CO is considered highly lethal....
9. Carbon monoxide (CO) is toxic because it can displace oxygen (O2) from the iron in hemoglobin (Hgb) following the reaction: HgbO2 (s) + CO(g) + Hgbco (s) + O2 (g) AG®rx = -30. kl/mol A.
