Question

Quizplus · Accepted Answer

Hemoglobin F (also known as fetal hemoglobin) has a higher affinity for oxygen and cannot bind to 2,3-DPG, which allows it to effectively extract oxygen from the mother's blood in the placenta and supply it to the developing fetus. Hemoglobin A, B, and G are all adult hemoglobins that are capable of binding to 2,3-DPG and have a lower affinity for oxygen to facilitate oxygen unloading in peripheral tissues.
