  1. The hemoglobin molecule
  2. The cell membrane lipid bilayer
  3. The cytoskeleton proteins
  4. The surface glycoproteins
Show answer and explanation

Correct answer: The cytoskeleton proteins

Defects in membrane proteins like spectrin cause the red blood cell to lose its biconcave shape and become spherical. These spherocytes are less flexible and are prematurely destroyed in the spleen.
