Which of the following is correct concerning the oxygenation plot of proteins X and Y shown below?

Question

Quizplus · Accepted Answer

Protein X exhibits a higher affinity for oxygen than protein Y, which means that it can bind to oxygen at lower partial pressures. Since fetal hemoglobin needs to be able to effectively bind oxygen from the mother's circulatory system, it has a higher affinity for oxygen than normal adult hemoglobin. Therefore, protein X with higher oxygen-binding affinity correspond to fetal hemoglobin and protein Y corresponds to normal adult hemoglobin.
