Question

which type of hemoglobin has the lowest affinity for oxygen?
embryonic
fetal
adult

Explanation:

Fetal hemoglobin has a higher affinity for oxygen than adult hemoglobin to facilitate oxygen - transfer from the mother to the fetus. Embryonic hemoglobin has an even higher affinity for oxygen compared to fetal and adult hemoglobin to meet the oxygen - demands of the developing embryo. Adult hemoglobin has the lowest affinity for oxygen among the three types mentioned as it needs to release oxygen more readily to the body's tissues.

Answer:

Adult
