how the protein structure surrounding the heme affects the relative affinity for oxygen vs. carbon monoxide.
Hemoglobin: binds oxygen with a higher affinity than myoglobin due to the presence of four heme groups vs. only one in myoglobin. binds oxygen with a lower affinity than myoglobin due to the presence of four heme groups vs. only one in myoglobin. binds to oxygen with a lower affinity than myoglobin due to the presences of the T-state that is absent in myoglobin. binds to oxygen with a higher affinity than myoglobin due to the presences of the R-state...
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....

How do DNA sequences change protein structure and what are some affects to the protein structures that can have an effect on the PTC receptor?
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...
