Question : Which of the following enzymes is essential for the clotting of blood?
Option 1: Amylase
Option 2: Thrombin
Option 3: Pepsin
Option 4: Renin
Correct Answer: Thrombin
Solution : The correct option is Thrombin.
Thrombin is an enzyme involved in blood clotting. Thrombin is an enzyme that plays an important role in blood coagulation, which is a series of processes that results in the creation of fibrin, a protein that forms the meshwork of a blood clot. Thrombin is essential in converting fibrinogen, an inert protein, into fibrin, which aids in clot stabilisation and prevents excessive bleeding.
