|
|
1, 3-bisphosphoglycerate
|

Phosphoenolpyruvate ____
|
Detailed explanation-1: -Enolase is used to convert 2-phosphoglycerate (2PG) to phosphoenolpyruvate (PEP) in the 9th reaction of glycolysis: it is a reversible dehydration reaction.. Enolase is expressed abundantly in most cells and has been proven useful as a model to study mechanisms of enzyme action and structural analysis.
Detailed explanation-2: -Step 7. In the seventh step, catalyzed by phosphoglycerate kinase (an enzyme named for the reverse reaction), 1, 3-bisphosphoglycerate donates a high-energy phosphate to ADP, forming one molecule of ATP.
Detailed explanation-3: -Step 2. In the second step of glycolysis, an isomerase converts glucose-6-phosphate into one of its isomers, fructose-6-phosphate. An isomerase is an enzyme that catalyzes the conversion of a molecule into one of its isomers.
