Given below are two statements.

Statement I: An enzyme complex called thrombokinase, is required for clot formation.

Statement II: Thrombokinase is formed by a series of linked enzymic reactions (cascade process) involving a number of factors present in plasma.

Choose the correct options given below.

Both statements are correct.

• Statement I: Thrombokinase is an enzyme complex required for clot formation.
• Statement II: A cascade process leads to the formation of an enzyme complex called thrombokinase.This enzyme that plays a central role in the clotting process. It catalyses the formation of thrombin from prothrombin. Thrombin in turn activates fibrinogen to fibrin leading to clot formation.
