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: Glycolysis Overview.
Glycolysis initiates with glucose, a six-carbon sugar, and systematically transforms it into pyruvate, yielding ATP and NADH.
Step 2: Key Stages.
- Initially, glucose is phosphorylated to hexose phosphates (C).
- These are then cleaved into triose phosphates (A).
- Triose phosphates undergo isomerization to form 2-phosphoglycerate (D).
- 2-phosphoglycerate is subsequently converted to phosphoenolpyruvate (B).
- Finally, phosphoenolpyruvate is dephosphorylated to pyruvate (E).
Step 3: Option Verification.
Option (D) accurately reflects the sequence: C → A → D → B → E.
Step 4: Final Determination.
The correct sequence for glycolysis is Hexose Phosphates → Triose Phosphates → 2-Phosphoglycerate → Phosphoenolpyruvate → Pyruvate.
