Sucrose-phosphate synthase (SPS) is a key enzyme in the biosynthesis of sucrose in plants. Following are certain statements regarding SPS:

A. Uridine-diphosphate glucose and fructose-6-phosphate are the substrates for SPS.

B. SPS directly converts its substrate into sucrose.

C. Phosphorylation activates while dephosphorylation inactivates SPS.

D. SPS converts its substrate into sucrose-6-phosphate which is then converted to sucrose by the action of sucrose-phosphate phosphatase.

E. Glucose 6-phosphate activates while Pi inactivates SPS.

Which one of the following options represents the combination of all correct statements?
