Question

Arrange the correct sequence of glycolysis pathway.
LIST:
A. Triose Phosphates
B. Phosphoenolpyruvate
C. Hexose Phosphates
D. 2-Phosphoglycerate
E. Pyruvate

• A. A, C, D, B, E
• B. C, D, A, B, E
• C. C, D, B, A, E
• D. C, A, D, B, E

Hint:

Think “Hexose → Triose → 2-Phosphoglycerate → PEP → Pyruvate” to recall glycolysis steps easily.

Answer 1

The Correct Option is D

Step 1: Recall glycolysis sequence.
Glycolysis begins with glucose, a hexose, and stepwise converts it into pyruvate, generating ATP and NADH.
Step 2: Major stages.
- First, glucose is converted into hexose phosphates (C).
- These are split into triose phosphates (A).
- The triose phosphates undergo rearrangements leading to formation of 2-phosphoglycerate (D).
- 2-phosphoglycerate is then converted to phosphoenolpyruvate (B).
- Finally, phosphoenolpyruvate is converted to pyruvate (E).
Step 3: Checking options.
Option (D) correctly follows the sequence: C → A → D → B → E.
Step 4: Conclusion.
The correct sequence of glycolysis is Hexose Phosphates → Triose Phosphates → 2-Phosphoglycerate → Phosphoenolpyruvate → Pyruvate.
