Enzyme in Glycolysis: Fructose-6-Phosphate Conversion

During cellular respiration, glucose undergoes several transformations to ultimately produce ATP, the energy currency of the cell. One key metabolic pathway involved in this process is glycolysis, which occurs in the cytoplasm of the cell. In glycolysis, glucose is broken down into two molecules of pyruvate. The conversion of glucose to pyruvate is crucial for cellular metabolism.

Several enzymes catalyze the reactions in glycolysis, and their activity can be regulated by various means, including feedback inhibition and allosteric regulation. Understanding these metabolic pathways is essential for comprehending how cells derive energy from nutrients.

Which of the following enzymes is specifically responsible for catalyzing the conversion of fructose-6-phosphate into fructose-1,6-bisphosphate in glycolysis?
