Final answer:
The transcobalamin II-B12 complex is indeed transported to the bone marrow for hematopoiesis and liver for storage. Vitamin B12 is critical for red blood cell production, and iron is also transported via transferrin to aid in this process.
Step-by-step explanation:
The statement that the transcobalamin II-B12 complex is transported to the bone marrow for hematopoiesis and the liver for storage is True. Vitamin B12 is essential for red blood cell formation and is carried by transcobalamin II to the bone marrow, where it is used in the synthesis of new red blood cells.
The liver acts as a storage site for excess Vitamin B12, which can be mobilized when needed. Additionally, iron, another crucial element, is carried through the bloodstream by the protein transferrin to the red bone marrow for incorporation into new erythrocytes and stored in the liver and spleen in the form of ferritin or hemosiderin.
Both processes are vital for maintaining healthy red blood cell levels and preventing anemia.
