Final answer:
Phosphogluco-isomerase is an enzyme that converts glucose 6-phosphate (G6P) into F6P, a crucial step in the glycolysis pathway, converting glucose into ATP and other energy-rich molecules.
Step-by-step explanation:
The reaction of Glucose 6-phosphate (G6P) to Fructose 6-phosphate (F6P) is catalyzed by the enzyme phosphogluco-isomerase. This enzyme converts G6P into one of its isomers, F6P. Isomers have the same chemical formula but different chemical structures.
During the process of glycolysis, G6P is converted to F6P in stage one. This conversion allows the molecule to be rearranged and split into two three-carbon structures, glyceraldehyde-3-phosphate and dihydroxyacetone phosphate, as part of the glycolysis pathway.
The conversion of G6P to F6P is an important step in the regulation and energy-consuming phase of glycolysis, where glucose is broken down to generate ATP and other energy-rich molecules.
