Question

Match the entries in Group I with that in Group II. 
     Group I                                      Group II 
P) Vitamin B1 \(\hspace{2cm}\) 1) Co-enzyme A 
Q) Vitamin B2 \(\hspace{2cm}\) 2) Flavin mononucleotide 
R) Vitamin B5 \(\hspace{2cm}\) 3) Pyridoxal phosphate 
S) Vitamin B6 \(\hspace{2cm}\) 4) Thiamine pyrophosphate 
 

• A. P-4, Q-3, R-2, S-1
• B. P-3, Q-1, R-4, S-2
• C. P-1, Q-2, R-3, S-4
• D. P-4, Q-2, R-1, S-3

Hint:

Each vitamin has a specific coenzyme form, which is essential for various enzymatic reactions in the body.

Answer 1

The Correct Option is D

Step 1: Understanding Vitamin Functions. 
- Vitamin B1 (P), also known as Thiamine, functions with the co-enzyme thiamine pyrophosphate. - 4 

- Vitamin B2 (Q), also known as Riboflavin, is a precursor for the coenzyme flavin mononucleotide (FMN). - 2

- Vitamin B5 (R), also known as Pantothenic acid, is a precursor to co-enzyme A. - 1

- Vitamin B6 (S), also known as Pyridoxine, is converted into pyridoxal phosphate, which acts as a coenzyme in amino acid metabolism. - 3
 

Step 2: Conclusion. 
The correct answer is (D) P-4, Q-2, R-1, S-3, as this correctly matches each vitamin with its associated coenzyme.
