(i) Enzyme
(ii) Vitamin
(iii) Metallic ion
Answer
i) Thrombin - it plays a crucial role in the conversion of fibrinogen (a soluble protein) into fibrin (insoluble threads), which forms the basis of a blood clot.
ii) Vitamin K - it is essential for the synthesis of several clotting factors in the liver, including prothrombin, which is a precursor to thrombin.
iii) Calcium Ion (Ca2+) - Calcium ions play a critical role in various steps of the clotting process, including the activation of factors that lead to the formation of fibrin threads from fibrinogen.
