Quizplus · Accepted Answer

Phosphorylation of glucose by hexokinase and phosphofructokinase is advantageous because it creates a concentration gradient that causes glucose from outside the cell to continue to move into the cytoplasm of the cell. This phosphorylated sugar cannot be transported back across the cell membrane, thus ensuring that glucose remains within the cell for utilization in cellular respiration. A phosphorylated sugar does not have less activation energy or is more likely to diffuse into the environment outside the cell.
