How is oxygen transport affected in a patient with a defect in beta globin chain production? A patient with a defect in alpha chain production?
What will be an ideal response?
Answer: Defects in globin chain production will impair hemoglobin production. Hemoglobin is the main oxygen-carrying protein, therefore oxygen transport will be impaired in both alpha and beta chain defects because less HbA will be formed. (Objective 2, Level II)
