Verified step by step guidance1
Understand the structure of adult hemoglobin, which is a protein responsible for transporting oxygen in the blood.
Recognize that hemoglobin is composed of four polypeptide chains, which are categorized into two types: alpha and beta chains.
Recall that adult hemoglobin, specifically hemoglobin A, consists of two alpha chains and two beta chains.
Differentiate between adult hemoglobin and fetal hemoglobin, noting that fetal hemoglobin contains two alpha and two gamma chains.
Identify that the correct composition of adult hemoglobin is two alpha and two beta chains, which is essential for its function in oxygen transport.
