Hemoglobin is a quaternary protein structure on a red blood cell involved in oxygen transport. Hemoglobin A1 has
two a-chains and two ß-chains. Hemoglobin A2 has two a-chains and two o chains. In spite of the structural
differences, both hemoglobin A1 and A2 perform the same functions.
Which of the following statements explains why both hemoglobin types perform the same functions?
O The amino acid sequence in the delta chain is not critical to oxygen transportation.
O Only the alpha chains are important for oxygen transport
O The delta chains are nonfunctional and the body compensates with more red blood cells.
O The amino acid sequences changed the alpha and beta chains because of molecular interaction.
