Administiring glucose-6-phosphate instead of glucose might save the patient ener!


Question: glucose is frequently administer intravenously (injected into the blood) to patient as a food source. a new resident at a hospital suggests administrating glucose- 6-phosphate instead of glucose . because transformation of glucose to glucose-6-phosphate requires ATP and you consider the possibility that administiring glucose-6-phosphate might save the patient energy. should you use the residents suggestion explain?

I would not follow the new resident's suggestion.
The phosphorylation of glucose adds a charged phosphate group so the glucose 6-phosphate cannot easily cross the cell membrane.
This may be a problem getting the G6P into the cell so that it can be used.
