O, saturation curve is shown beloww for hemoglobin at various pHs. Detail this Bohr effect from the molecular perspective. Be sure to include discussion of what causes this (i.e. specific amino acids), why the curves are right shifted with decreasing pH, and why this is logical in delivery of 02 to areas of higher demand. 100 Myoglobin 80- pH 7.6 60 pH 7.4 pll 7.2 40- pH 7.0 pH 6.8 20- Venous 0- 0. 20 10 60 80 Percent saturation

Hemoglobin retains less O2 at pH 7.4 compared to pH 7.2. B. Hemoglobin retains less O2 at pH 7.2 compared to pH 7.4. C. The release of O2 from hemoglobin is not influenced by the production of CO2. D. At pH 7.2 where CO2 production is less than pH 7.4, hemoglobin releases less O2.
0.3 M Glycerin, 0.3 Urea are both 0.3, but thei effect on RBCs is very different than 0.3 M Glucose. Glycerin = glycerol, which is a non-polar molecule. Urea is a small molecule which passes though membrane easily by facilitated diffusion. Predict the fate of a red blood cell placed in 0.3 M glycerin and in a 0.3 M Urea. Explain why these changes might take place.
