Question

What is the function of thromboplastin? Explain.

Answer 1

Hint: This enzyme is called thrombokinase is delivered from injured or damaged cells, especially the platelets. They convert prothrombin to thrombin during the first stages of blood clotting.

Complete answer:
Thromboplastin is a mixture of both phospholipids and a posh enzyme that's found in the brain, lung, and other tissues and particularly in blood platelets. Its main function is to convert prothrombin to thrombin within the clotting of blood.
The platelets and injured tissue release thromboplastin, which initiates the formation of enzyme prothrombinase within the blood. The prothrombinase in presence of Ca ions converts inactive protein called prothrombin into active thrombin. The thrombin converts soluble fibrinogen into insoluble fibrin. The fibrin fibers enmesh platelets, blood cells, and plasma to make the clot.

Additional Information: -From the very fact that the blood doesn't normally clot within the vessels, it's going to be inferred that intrinsic blood thromboplastin is either very feeble or exists in an inactive form.
-To obtain conclusive results the components essential for thromboplastin formation must be separated from the blood, shown to be free from prothrombin, and, after their interaction, the activity of the merchandise must be tested by its ability to clot normal plasma.
-The purpose of this communication is to demonstrate that blood thromboplastin is made from the three components, platelets, antihemophilic factors, and a serum fraction.

Note: When thromboplastin is manipulated in the laboratory, a derivative could be created called partial thromboplastin. Partial thromboplastin is just phospholipids, and not tissue factor and was used to measure the intrinsic pathway.
