Phosphorylation of Glucose Following Its Transport into a Cell

Phosphorylation of glucose following its transport into a cell

A) targets the glucose for transport back out of the cell.
B) decreases glucose transport into the cell by decreasing its concentration gradient across the plasma membrane.
C) increases glucose transport into the cell by increasing its concentration gradient across the plasma membrane.
D) converts glucose into a form that can more easily be exported from the cell.
E) maintains a higher level of glucose outside the cell.
