Question

What transfers between 2 phosphoglycerate and phosphoenol pyruvate?

1) Oxygen
2) Carbon dioxide
3) Phosphate group
4) Hydrogen ions

Answer 1

During glycolysis, water is removed from 2-phosphoglycerate to form phosphoenolpyruvate via a dehydration reaction catalyzed by enolase.

Step-by-step explanation:

The transfer that occurs between 2-phosphoglycerate (2-PG) and phosphoenolpyruvate (PEP) during glycolysis is dehydration, where water (H₂O) is removed from 2-phosphoglycerate to form phosphoenolpyruvate. The reaction is catalyzed by the enzyme enolase. This process does not involve the transfer of a phosphate group, carbon dioxide, or hydrogen ions as the focus here is on the conversion between these two specific compounds in the metabolic pathway.
