Question

Match the metabolic pathways in Group A with corresponding enzymes in Group B 

 

• A. P: i, Q: iv, R: iii, S: ii
• B. P: ii, Q: i, R: iv, S: iii
• C. P: i, Q: iv, R: i, S: iii
• D. P: iii, Q: iv, R: ii, S: i

Hint:

To match enzymes with their pathways, remember that glycolysis involves enolase, gluconeogenesis involves pyruvate carboxylase, and the pentose phosphate pathway involves glucose-6-phosphate dehydrogenase.

Answer 1

The Correct Option is B

Step 1: Understanding the metabolic pathways.
- P: Glycolysis involves the breakdown of glucose to pyruvate. The enzyme Enolase plays a key role in the conversion of 2-phosphoglycerate to phosphoenolpyruvate.
- Q: Gluconeogenesis is the process of forming glucose from non-carbohydrate precursors, and it involves Pyruvate carboxylase.
- R: Hexose monophosphate shunt (also called the pentose phosphate pathway) involves the enzyme Glucose-6-phosphate dehydrogenase.
- S: Glyoxylate cycle is similar to the citric acid cycle and involves Isocitrate lyase.
Step 2: Conclusion.
The correct matching is:
- P: ii (Enolase)
- Q: i (Pyruvate carboxylase)
- R: iv (Glucose-6-phosphate dehydrogenase)
- S: iii (Isocitrate lyase)
Thus, the correct answer is (B).
