Question

Identify the correct sequence of blood coagulation (a) Activation of prothrombin (b) Formation of prothrombin activator (c) Formation of blood clot (d) Conversion of fibrinogen to fibrin

• A. b - d - a - c
• B. b - a - d - c
• C. a - d - c - b
• D. a - b - c - d

Answer 1

The correct option is B b - a - d - c

Blood coagulation occurs in the following sequence:

• Whenever there is rupture of blood vessels or damage is caused to blood, a complex of substances called prothrombin activator complex is formed.
• The activators convert prothrombin into thrombin.
• Thrombin acts as an enzyme and converts fibrinogen into fibrin threads.
• Fibrin threads accumulate and clump to form blood clot at the wound site.

So, the correct answer is 'b- a- d- c'.
