Select the BEST answer. The percentage oxyhaemoglobin in a haemoglobin solution can be calculated by: using the ratio of absorbances of oxy- and deoxyhaemoglobin at wavelengths where the biggest difference in absorbance readings are observed between the two forms. adding a live yeast suspension to an oxyhaemoglobin solution and observe the change in absorbance by spectrophotometry. measuring the absorbance of an oxyhaemoglobin solution using the wavelength that corresponds to its a...
