Question

Fibrinogen and prothrombin are both involved in formation of blood clots when they are converted into proteolytic enzymes. However, they are normally found in the blood in an inactive form. Develop an explanation for this observation.

Answer 1

when ever rupturing of tissues takes place then prothrombin( an inacive enzyme) is converted into thrombin ( an active enzyme) that foms an inactive and soluble fibrinogen enzyme which inturn produce fibrin active and insoluble enzyme. Generally inactive enzymes prothrombin and fibrinogen are present in blood.after rupturing of tissues they immediately produce active enzymes thrombin and fibrin. Which are further used for clotting of blood. For producing active enzymes, prothrombin and fibrinogen are present in blood. The active enzymes clot the blood.
