Answer
Vitamin K
Explanation
Vitamin K is the crucial vitamin responsible for the coagulation or clotting of blood. Its chemical name is Phylloquinone. It acts as a coenzyme in the synthesis of prothrombin and other blood-clotting factors in the liver. Without adequate Vitamin K, even a minor cut could lead to excessive bleeding.
Key Points
- > Chemical name: Phylloquinone (K1) or Menaquinone (K2).
- > It is a fat-soluble vitamin.
- > The mineral essential for blood clotting is Calcium (\( Ca^{2+} \)).
- > The blood cells responsible for clotting are Platelets (Thrombocytes).
- > Vitamin A is for vision, C is for immunity/scurvy, D is for bone health.
- > Deficiency of Vitamin K leads to delayed blood clotting.
- > Green leafy vegetables are rich sources of Vitamin K.
