Enzyme Classification in Glycolysis

Glucose metabolism is a crucial biochemical pathway that involves a series of enzymatic reactions. One specific reaction converts glucose-6-phosphate into fructose-6-phosphate, which is an important step in glycolysis. This transformation is catalyzed by an enzyme that is most notably classified as an isomerase. Understanding the structural changes and mechanisms involved in this reaction is vital for comprehending carbohydrate metabolism.

Which of the following enzyme types is responsible for this conversion of glucose-6-phosphate to fructose-6-phosphate?
