Biomolecules · Class 12 · JEE Main Previous Year Question
Deficiency of vitamin K causes:
- a
Cheilosis
- b✓
Increase in blood clotting time.
- c
Decrease in blood clotting time.
- d
Increase in fragility of RBC's.
Increase in blood clotting time.
Step 1: Vitamin K Role — Vitamin K is indispensable for the activation of clotting factors (like prothrombin) in the liver.
Step 2: Analyzing Deficiency Effects — When vitamin K is deficient, the blood’s ability to coagulate is impaired, resulting in abnormal and prolonged bleeding.
Step 3: Result — This condition is clinically measured as an increase in blood clotting time. Thus, (b) is the correct deficiency symptom.
Remember: Other vitamin deficiencies lead to conditions like cheilosis () or RBC fragility (E).
