Question

Following are different stages in blood clotting. Arrange them in correct sequence:
[I)] Activation of prothrombin
[II)] Formation of prothrombin activator
[III)] Conversion of fibrinogen into soluble fibrin
[IV)] Clot retraction
[V)] Conversion of soluble fibrin into insoluble fibrin threads

• A. II, I, V, III, IV
• B. II, I, III, V, IV
• C. I, II, III, IV, V
• D. IV, V, III, I, II

Hint:

Remember the sequence: \textbf{Activator → Prothrombin → Fibrinogen → Fibrin threads → Clot retraction}.

Answer 1

The Correct Option is B

The correct order of events in blood clotting is: % Option (A) Formation of prothrombin activator (II) % Option (B) Activation of prothrombin (I) % Option (C) Conversion of fibrinogen into soluble fibrin (III) % Option (D) Conversion of soluble fibrin into insoluble fibrin threads (V) % Option (E) Clot retraction (IV)
