Conversion of Prothrombin into Active Thrombin by Thromboplastin
Thromboplastin is an enzyme that is released from damaged tissues and initiates the clotting process by converting prothrombin into active thrombin. This conversion requires the presence of certain cations, including:
- Calcium ions (Ca2+)
- Magnesium ions (Mg2+)
Out of these two cations, calcium ions are the most important for the conversion of prothrombin into active thrombin. This is because calcium ions:
- Bind to thromboplastin and activate it, allowing it to convert prothrombin into thrombin
- Bind to certain clotting factors, including factor X, which is required for the formation of the prothrombinase complex that converts prothrombin into thrombin
Therefore, the correct answer to the question is option D, Ca2+.
