1. Fetal erythrocytes contain a structural variant of hemoglobin, HbF, consisting of two a and two y subunits (azy), whereas maternal erythrocytes contain HbA (022). Consider the oxygen saturation curve shown below and answer the questions that follow: a) Which hemoglobin has a higher affinity for oxygen? Explain how you made that interpretation. +BPG 0.5 -BPG b) What is the physiological significance of the different 02 affinities? 8 10 4 6 po, kPa) 2. In the context of O, binding...
In plain language, describe what the oxygen-hemoglobin dissociation curve shows. Under normal conditions, the curve can shift to the right and left. A right shift can be induced by increased temperature and lower pH among other things. Describe what a right shift means in terms of hemoglobin’s relationship to oxygen. In your answer, be sure you address what is actually happening at the level of the protein (hemoglobin is a protein). Discuss what types of molecular interactions that can cause...
