Options
(a) thrombin
(b) fibrinogen
(c) prothrombin
(d) thrombokinase
Correct Answer:
thrombokinase
Explanation:
Thrombokinase is an enzyme secreted by the damaged tissues and blood platelets to convert a soluble protein in the blood stream, prothrombin into thrombin. Thrombin increases the rate of chemical reaction to form a network of insoluble fibrin, over the wound. When thrombokinase is released, it neutralizes the action of heparin (anticoagulant) so that clotting can effectively take place.
