Which one of the following conversion in glycolysis shows formation of water molecules from the substrate?
Options
- AFructose 6 phosphate \rightarrow Fructose 1,6 diphosphate
- BPhosphoenolpyruvate \rightarrow Pyruvic acid
- C2 Phosphoglycerate \rightarrow 2 Phosphoenolpyruvate
- DGlyceraldehyde 3 phosphate \rightarrow 1,3 diphosphoglycerate
Correct answer
C. 2 Phosphoglycerate \rightarrow 2 Phosphoenolpyruvate
Step-by-step solution
In glycolysis, the conversion of 2-phosphoglycerate to phosphoenolpyruvate is catalyzed by the enzyme enolase.
This step involves the elimination of a water molecule (dehydration) from 2-phosphoglycerate to form the enol structure of phosphoenolpyruvate.
Therefore, the formation of a water molecule occurs during the conversion of 2-phosphoglycerate to phosphoenolpyruvate.
Answer: 2 Phosphoglycerate \rightarrow 2 Phosphoenolpyruvate
This step involves the elimination of a water molecule (dehydration) from 2-phosphoglycerate to form the enol structure of phosphoenolpyruvate.
Therefore, the formation of a water molecule occurs during the conversion of 2-phosphoglycerate to phosphoenolpyruvate.
Answer: 2 Phosphoglycerate \rightarrow 2 Phosphoenolpyruvate
