Question

Which vitamin is necessary for clotting of blood ?

• A. A
• B. B
• C. C
• D. K

Answer 1

The Correct Option is D

To solve the problem, we need to identify which vitamin is essential for the clotting of blood.

1. Understanding Blood Clotting:
Blood clotting, also known as coagulation, is a complex process that prevents excessive bleeding when blood vessels are injured. It involves a series of chemical reactions and the activation of various proteins in the blood. Several factors contribute to this process, including platelets, clotting factors, and specific vitamins.

2. Role of Vitamin K:
Vitamin K plays a crucial role in blood clotting because it is necessary for the synthesis of several clotting factors in the liver. These clotting factors (such as Factor II, VII, IX, and X) are required for the formation of a stable blood clot. Without sufficient Vitamin K, the body cannot produce these factors effectively, leading to impaired clotting and increased risk of bleeding.

3. Other Vitamins:
- Vitamin A: Essential for vision, immune function, and cell growth but not directly involved in blood clotting.
- Vitamin B: Important for energy metabolism and nerve function but does not play a direct role in clotting.
- Vitamin C: Necessary for collagen synthesis and wound healing but not directly involved in the clotting process.

4. Conclusion:
The vitamin that is necessary for the clotting of blood is Vitamin K.

Final Answer: (D): K
