A patient is diagnosed with thrombocytopenia. Which molecule, crucial for platelet production, might be decreased or dysfunctional in their system?

A. Thrombopoietin
B. Fibrin
C. Thromboxane A2
D. Prothrombin



Answer :

Final answer:

Thrombopoietin is the key molecule for platelet production in thrombocytopenia.


Explanation:

Thrombopoietin is the crucial molecule for platelet production that might be decreased or dysfunctional in a patient diagnosed with thrombocytopenia. Thrombopoietin stimulates precursor cells in the bone marrow to differentiate into megakaryocytes, which generate platelets essential for blood clotting.

When platelet counts are low, more Thrombopoietin becomes available to stimulate megakaryocytes to replenish the platelet supply. This hormone plays a significant role in maintaining the balance of platelet production in the body.
