Correct option is D
Correct Answer:
Option 4
Explanation: The reaction shown involves an
intramolecular transfer of a phosphate group within a glycerate molecule, converting one bisphosphorylated form into another without ATP consumption or redox change.
Bis-phosphoglycerate mutase catalyzes such rearrangement reactions, particularly involving
1,3-bisphosphoglycerate and 2,3-bisphosphoglycerate in glycolytic side pathways. The other enzymes listed either catalyze ATP-dependent phosphorylation, dephosphorylation, or unrelated metabolic steps, making them incorrect.
