Catalyzation of prothrombin into thrombin

  • The prothrombinase inactivates heparin (anti-coagulant) in the presence of calcium
  • Enzyme prothrombinase catalyzes the breakdown prothrombin (inactive plasma protein) into an active protein called thrombin 
  • Prothrombin is factor II. It is glycoproteinaceous and synthesised in the liver by vitamin K

The mineral required for the conversion of prothrombin into thrombin is calcium. Hence, the correct answer is option b.
