Final answer:
Factor Xa is an important component of the coagulation cascade in the process of blood clotting. It converts prothrombin into thrombin, which helps produce fibrin for clot formation.
Step-by-step explanation:
Factor Xa is an important component of the coagulation cascade in the process of blood clotting. It is activated through either the intrinsic or extrinsic pathway and plays a crucial role in the production of fibrin, which helps seal off blood vessels. Factor Xa converts prothrombin, an inactive enzyme, into thrombin, an active enzyme that then converts fibrinogen into fibrin.
