B: Bilirubin is placed in long-term storage in the liver.
C: The iron ions in hemoglobin are removed.
D: The iron ions are stored in the liver.
E: The iron ions are stored in the red bone marrow.f: Membrane proteins and globin proteins are broken down and reused.g: The erythrocyte contents,excluding the globins,are excreted unchanged via the digestive tract.

Question

Quizplus · Accepted Answer

The options that are true are C and F. The iron ions in hemoglobin are removed (C) and membrane proteins and globin proteins are broken down and reused (F). Option A is incorrect because biliverdin is further converted into bilirubin before being placed in long-term storage in the liver. Option D is incorrect because while the iron ions are stored in the liver, they are not stored exclusively in the liver. Option E is incorrect because while the iron ions are stored in the red bone marrow, they are not stored exclusively in the red bone marrow. Option G is incorrect because erythrocyte contents, excluding globins, are not excreted unchanged via the digestive tract, but rather the breakdown products of hemoglobin are ultimately excreted in the stool.
