... (1) glucose 6-phosphate cannot diffuse through the membrane, because of its negative charge ---> trapping glucose in cell (2) the addition of phosphoryl group begins to destabilize glucose... seems that the first two answers are right... but as you said the last answer seems to be right too: ...
