Question

Antihemorrhagic vitamin is:
(A) A
(B) $ {{\text{B}}_{\text{1}}} $
(C) K
(D) C

Answer 1

Hint: Haemorrhage is simply “bleeding” and is used to describe blood loss. It can also refer to blood loss inside the body, called internal bleeding, or blood loss outside of the body, called external bleeding. Blood loss can occur in any part of the body. The vitamin which helps in clotting is found in leafy vegetables.

Complete Step by Step Answer
The word “Anti haemorrhagic” refers to anything that helps the blood to clot to stop the bleeding. So “Antihemorrhagic” vitamin is that one which helps in blood clotting. Let us have a look at the process of blood clotting.
Blood-clotting is an important process that prevents excessive bleeding when a blood vessel gets cut or wounded. The platelets and the plasma of the blood together work to form the clot and stop the bleeding.
In the presence of the plasma proteins and the calcium ions, the enzyme, Prothrombin Activator is activated which in turn converts the Prothrombin into Thrombin. Thrombin is that enzyme that converts the fibrinogen to fibrin. Thus the strands of fibrin protein stick to the platelets and the endothelial cells at the wound form a meshwork that in turn traps other cells. Vitamin K plays an important role in this process of clot formation.
Hence, the correct answer here is option C.

Note
Vitamin K is a fat-soluble vitamin that is mostly found in green leafy vegetables as it is directly involved in the processes of photosynthesis. Animal products also include this vitamin but the amount is lesser than that of the plants and plant products. The deficiency of this vitamin leads to the difficulty in the formation of the blood clots.
