Which of the following statements explain why red blood cells
(RBCs) are highly specialized for oxygen transport?
(1) RBCs contain hemoglobin.
(2) RBCs lack a nucleus.
(3) RBCs have many mitochondria and thus generate ATP aerobically.
(4) The biconcave shape of RBCs provides a large surface area for the inward and outward diffusion of gas molecules.
(5) RBCs can carry up to four oxygen molecules for each hemoglobin molecule.
(a) 1, 2, 3, and 5 (b) 1, 2, 4, and 5 (c) 2, 3, 4, and 5
(d) 1,3, and 5 (e) 2, 4, and 5
