Answer 2

Calcium is an activated factor.

Option: B

Explanation:  

• Clotting cascade has thirteen factors. Fibrinogen is factor 1, Prothrombin is factor 2, Stuart power factor is factor 10.  

• Among this calcium is always an active factor. The other factors need to get activated.  

• Calcium has a role in both intrinsic and extrinsic pathway of coagulation.  

• Calcium ion falls under the clotting factor 4. Calcium along with vitamin K in the presence of fibrinogen protein are the main proteins which help in coagulation.  

• In blood banks for this reason calcium needs to be chelated to prevent clotting.
