Question

Formation of a to b is carried out in the presence of Ca⁺⁺ions during clotting.

Select the CORRECT option for a and b

पर्याय

• a - prothrombinase; b - thrombin

• a - thromboplastin; b - prothrombin

• a - prothrombin; b - thrombin

• a - fibrin; b - fibrinogen

Answer 1

a - prothrombin; b - thrombin

Explanation:

Damaged platelets release thromboplastin, an initial clotting factor that starts the activation of different enzymes in the presence of Ca⁺⁺ in the blood. For the clotting mechanism, prothrombin is converted to thrombin, and fibrinogen is converted to fibrinogen.
