Answer to Question 1

ANS: A
The affinity of hemoglobin for oxygen is high in the lungs, so that loading of hemoglobin with oxygen is facilitated. It is lower in tissue to facilitate the delivery of oxygen to tissue.

Answer to Question 2

ANS: C
Globin chains are synthesized on the ribosomes in the cytoplasm of a developing RBC; heme synthesis takes place primarily in the mitochondria.
