Question

Match the items in List I with items in List II

 

• A. A – III, B – IV, C – II, D – I
• B. A – II, B – IV, C – I, D – III
• C. A – IV, B – II, C – III, D – I
• D. A – III, B – II, C – IV, D – I

Hint:

Remember to associate enzymes with pathways by their primary regulatory or rate-limiting role. For example, PFK-I is central to glycolysis, while Rubisco is unique to the Calvin cycle.

Answer 1

The Correct Option is C

Step 1: Match the pathways with their characteristic enzymes.
$\beta$-Oxidation: Involves the breakdown of fatty acids; Thiolase catalyzes the cleavage of carbon-carbon bonds — Match: A – IV
Glycolysis: The key regulatory enzyme is Phosphofructo kinase-I (PFK-I) — Match: B – II
Gluconeogenesis: A key enzyme unique to this pathway is Phosphoenolpyruvate carboxylase — Match: C – III
Calvin cycle: In photosynthetic organisms, Ribulose Bisphosphate Carboxylase (Rubisco) is the primary enzyme — Match: D – I
Step 2: Final matching
A – IV (Thiolase)
B – II (Phosphofructo kinase-I)
C – III (Phosphoenolpyruvate carboxylase)
D – I (Ribulose Bisphosphate Carboxylase)
