Question

6. Which of the following amino acid residues would provide a side chain capable of increasing the hydrophobicity of a binding site? A) aspartic acid B) lysine C) isoleucine D) arginine E) serine 7. Consider a hypothetical hemoglobin with a Hill coefficient of 1 and the same pso value as normal hemoglobin. Choose the statement below that best describes the two proteins. A) There is a cooperative interaction between oxygen-binding sites in both the hypothetical and normal hemoglobins. B) The hypothetical hemoglobin has a greater oxygen affinity than normal hemoglobin. C) The oxygen binding curve for the hypothetical hemoglobin is hyperbolic, and the curve for normal hemoglobin is sigmoidal. D) The two hemoglobins would be able to deliver about the same amount of oxygen to the tissues. E) At pO2 less than pso, normal hemoglobin has a greater Yor value.
