Art a: describe why, according to the hemoglobin /oxygen binding curve, a reduction in oxygen saturation from 95% to 85% is potentially dangerous part b: assume you have a volume of blood containing unknown concentrations of oxygenated hemoglobin (hbo) and deoxygenated hemoglobin (hb). using the beer-lambert law, calculate the concentration of each species (in moles/iter), as well as the oxygen saturation assuming the following conditions 1. 2. 3. the volume of blood is placed in a standard spectrophotometer cuvette (1 cm sides) assume scattering is negligible the absorbance of the blood volume is measured at two distinct wavelengths. 650nm anda 950nm the molar extinction coefficients for these species at the indicated wavelengths (in units of cm (moles/liter)) are fora for λ 650nm, еньо 950nm, еньо 300 and eh-2000 1200 and ehd-600 a. b. 4. absorbance at 650nm is 1.54 5. absorbance at λ = 950nm is 2.46
