Question:

Which of the following plasma protein helps in coagulation of blood?

Options:

1. Fibrin
2. Prothrombin
3. Vitamin K
4. Albumin

Solution:

Prothrombin is a plasma protein produced by the liver and is an essential component of the blood clotting process. It is converted to its active form, thrombin, during the clotting cascade, which is triggered by injury to a blood vessel. Thrombin then acts as an enzyme to convert the soluble plasma protein fibrinogen into insoluble fibrin strands, which form the structural basis of a blood clot. Fibrin, listed as option 1, is actually the product of the action of thrombin on fibrinogen, and not a plasma protein itself. Vitamin K, listed as option 3, is important for the production of several clotting factors in the liver, but is not itself a plasma protein. Albumin, listed as option 4, is a plasma protein that is involved in maintaining oncotic pressure and transporting various substances in the blood, but is not directly involved in blood clotting.
