Which of the following depicts the correct sequence of protein activity in clot formation?
A) Thrombin → prothrombin → fibrinogen → fibrin
B) Prothrombin → thrombin → fibrinogen → fibrin
C) Prothrombin → thrombin → fibrin → fibrinogen
D) Prothrombin → thrombin → fibrin
E) Prothrombin → thrombin → fibrinogen → erythrocytes
Clot Formation
The process by which blood changes from a liquid to a gel, forming a clot, which is essential in preventing excessive bleeding when blood vessels are injured.
Thrombin
An enzyme in blood plasma that causes the clotting of blood by converting fibrinogen to fibrin.
Prothrombin
A protein present in blood plasma that is converted into active thrombin during coagulation, playing a key role in blood clot formation.
- Elucidate the sequence of events in blood clotting and identify the factors that either facilitate or hinder coagulation.

Final Answer :
B
Explanation :
The correct sequence for protein activity in clot formation starts with the conversion of prothrombin to thrombin. Thrombin then converts fibrinogen, a soluble protein, into fibrin, an insoluble protein that forms the meshwork of the clot.
