Question

What is the role of thromboplastin in blood clotting?

Answer 1

Blood clot:

1. A blood clot is a mass of blood that forms when platelets, proteins, and cells in the blood stick together.
2. Thromboplastin is a complex enzyme that is found in the brain, lung, and other tissues and especially in blood platelets, and that functions in the conversion of prothrombin to thrombin in the clotting of blood.

Role of thromboplastin in blood clotting:

1. Thrombokinase or Thromboplastin (TPL) is a complex found specifically in platelets.
2. It is a mixture of tissue factors and phospholipids present in plasma assisting the blood to coagulate.
3. It is achieved through the catalysis of converting prothrombin to thrombin.
