Y (fraction saturation) 1.0 0.8 0.6 0.4 0.2 0.0 0 20 Oxygen Binding plot 60 p02 (torr) 40 80 100 A) Curve x = adult haemoglobin, curve y = fetal haemoglobin B) Curve x = myoglobin, curve y = haemoglobin C) Curve x = fetal haemoglobin, curve y = adult haemoglobin D) Curve x = fetal haemoglobin, curve y = myoglobin E) Curve x = adult haemoglobin, curve y - myoglobin

Which of the following is the concentration of hemoglobin-bound oxygen in the blood when the heme is fully saturated? 8500 uM 8630 uM 2200 uM 8800 uM

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…

Suppose you visit the Dalai Lama in Dharamsala, India (elevation 1460 m),and you begin to ponder the “big questions,” such as “What is the fractionalsaturation of the Dalai Lama’s hemoglobin?”(a) Assuming the Dalai Lama’s hemoglobin has a Hill coefficient = 3.2,and a P50 = 31 mm Hg, calculate the change in fractional O2 saturationof his hemoglobin going from his lungs (where PO2 = 85 mm Hg) to hiscapillaries (where PO2 = 25 mm Hg).(b) Why do you suppose the Dalai Lama’s hemoglobin has a P50 higher thannormal (where “normal” = 27 mm Hg)?

Can you please answer these three sub questions and explain please thank you
