1. Glucose gets a phosphate. Glucose → Glucose-6-phosphate. What is the name of the step?
Process: Phosphorylation of Glucose. Enzyme: Hexokinase. Molecule: glucose
2. Shape changes from a 6-ring to a 5-ring sugar. Glucose-6-phosphate → Fructose-6-phosphat. Glucose is rearrangede
Process: Isomerization. Enzyme: phosphoglucose isomerase. Molecule: fructose-6-phosphate.
3. Fructose-6-phosphate + ATP → Fructose-1,6-bisphosphate. Another phosphate is added
Process: Second phosphorylation. Enzyme: phospofructokinase. Molecule: fuctose 1,6 biphosphate.
