Question

The deficiency of vitamin (X) causes convulsions. Source of X is Y. What are X and Y ?

• A. Riboflavin, milk
• B. Riboflavin, fish
• C. Pyridoxine, curd
• D. Pyridoxine, cereals

Hint:

To solve questions about vitamin deficiencies and their sources, it's helpful to remember key vitamins and their associated symptoms and common dietary sources: Vitamin B6 (Pyridoxine):} Essential for amino acid metabolism and neurotransmitter synthesis. Deficiency can lead to neurological problems like convulsions, as well as anemia. Good sources include meat, fish, poultry, whole grains, nuts, and some fruits and vegetables. Vitamin B2 (Riboflavin):} Involved in energy metabolism. Deficiency causes ariboflavinosis (cheilosis, glossitis, skin inflammation). Sources include milk, dairy products, eggs, meat, and leafy greens. Memorizing these associations helps in quickly identifying the correct pair.

Answer 1

The Correct Option is D

Step 1: Identify Vitamin (X) that causes convulsions due to deficiency.
Convulsions are neurological symptoms that can be caused by the deficiency of certain vitamins. Among the options provided, Pyridoxine deficiency is well-known to cause neurological issues, including convulsions. Riboflavin (Vitamin B2): Deficiency of riboflavin causes ariboflavinosis, symptoms of which include cracks and sores at the corners of the mouth (cheilosis), inflammation of the tongue (glossitis), and skin disorders. It is not primarily associated with convulsions.
Pyridoxine (Vitamin B6): Deficiency of pyridoxine can lead to neurological symptoms such as seizures or convulsions, especially in infants. It is crucial for the synthesis of neurotransmitters. Therefore, Vitamin (X) is Pyridoxine. 
Step 2: Identify a common source (Y) of Vitamin X (Pyridoxine).
Now that X is identified as Pyridoxine, we need to find its source (Y) from the options. 
Milk: While milk contains some B vitamins, it is not a primary or most significant source of pyridoxine.
Fish: Fish is a good source of several vitamins, including some B vitamins, but it is not the most commonly cited broad source associated with this question's options.
Curd: Curd (yogurt) contains B vitamins, but again, it's not the primary or most impactful source for pyridoxine in the context of the options.
Cereals: Whole grain cereals, fortified cereals, and many types of grains are excellent sources of Pyridoxine (Vitamin B6).
Therefore, a significant source (Y) of Pyridoxine (X) is cereals. 
Step 3: Combine X and Y to find the correct option.
Based on the analysis, X is Pyridoxine and Y is cereals. |
This matches option 4.
