The following graph shows partial saturation (Y) of myoglobin (Mb), adult hemoglobin (HbA) and fetal hemoglobin (HbF) as a function of partial oxygen pressure (in mmHg). Use it to answer the question: Fetal hemoglobin ( biological function: HbF) demonstrates lower p50 than adult hemoglobin (HbA). This adaptation has the following A. Allow fetal hemoglobin form pentamer subunits. B. HbF has lower affinity for for O2 compared to adult Hb C. Allow fetal hemoglobin to effectively intercept oxygen from mother's hemoglobin. D. Allow fetal hemoglobin to replace myoglobin in muscles
