Which process is represented by 'Glucose -> G6P -> F6P -> F1-6BiP'?

• A. Glycogen synthesis
• B. Glycolysis
• C. Gluconeogenesis
• D. Cellular respiration

Answer: (B)

The sequence 'Glucose -> G6P -> F6P -> F1-6BiP' describes a series of transformations that occur during the glycolytic pathway, which is a crucial metabolic process. In glycolysis, glucose is first phosphorylated to form glucose-6-phosphate (G6P) through the action of the enzyme hexokinase. This reaction is critical because it helps trap glucose within the cell and makes it more chemically reactive. Next, G6P is isomerized to fructose-6-phosphate (F6P) by the enzyme phosphoglucose isomerase. This conversion is an essential step as it prepares the molecule for further phosphorylation. Finally, F6P is then phosphorylated to fructose-1,6-bisphosphate (F1,6BiP) by the enzyme phosphofructokinase (PFK), which is a key regulatory step in the glycolytic pathway that commits the substrate to be metabolized for energy (ATP production). This series of reactions exemplifies the preparation phase of glycolysis, highlighting a pathway that primarily focuses on the breakdown of glucose into pyruvate, resulting in the production of ATP. Therefore, this sequence directly correlates with glycolysis
