Glucose is converted into glucose 6-phosphate by hexokinase.  Glucose 6-phosphate then serves as the substrate for the enzyme phosphoglucose isomerase, which converts this reactant into fructose 6-phosphate. Fructose 6-phosphate serves as the substrate for phosphofructokinase, which converts fructose 6-phosphate into fructose 1,6-bisphosphate.  Based on the information provided, this is an example of what?

A. Feedback inhibition
B. A metabolic pathway
C. Allosteric regulation
D. Enzyme inhibition
