35)Which of the following is correct concerning the oxygenation plot of proteins X and Y shown below?
A)Protein Y exhibits tighter oxygen binding than protein X.B)Protein Y would function as a better oxygen-transport protein than protein X.C)Protein X exhibits cooperative binding, whereas Y does not.D)Protein Y corresponds to myoglobin, and protein X corresponds to hemoglobin.E)Protein X contains multiple binding sites.Ans: B Section: 7.236)Which is NOT correct concerning the accepted models that describe cooperative binding?37)Consider the oxygen-binding profile at three different pH values of 7.6, 7.4, and 7.2. Which statement is most correct?
38)What would be the expected result of a Lys residue being replaced by a Ser residue in the BPG binding site of hemoglobin?Short-Answer Questions39)Why is it advantageous for hemoglobin to have allosteric properties?
Ans:Hemoglobin binds oxygen in a positive cooperative manner. This allows it to become saturated in the lungs, where oxygen pressure is high. When the hemoglobin moves to tissues, the lower oxygen pressure induces it to release oxygen and thus deliver oxygen where it is needed. Section: 7.240)What is fetal hemoglobin? How does it differ from adult hemoglobin?
