Below are multiple oxygen binding affinity curves for hemoglobin. The affinity curve for normal hemoglobin in blood is represented by curve "D," at a pH of 7.2 and at a concentration of 5mM BPG and 26 mM CO2. O₂ saturation (%) 100 Answer 1: B Answer 2: [Select] Answer 3: B Answer 4: 80 A 60 1. How would changes to acidity, BPG concentration and CO₂ levels affect the binding affinity curve and p50? lower than Answer 5: E 40 1. BPG concentration is decreased to 3mM: The binding affinity curve would look like B. The p50 would be lower than normal (D). 2. pH is increased to 7.6: The binding affinity curve would look like B. The p50 would be [Select] normal (D). 20 3. CO₂ concentration is increased to 30 mM: The binding affinity curve would look like. [Select] The p50 would be Answer 6: 0 normal (D). II. The hemoglobin has been treated with a denaturing solution which disrupts quaternary structure only, and has a binding affinity resembling myoglobin. The binding affinity curve would look…
