What is the significance of the fact that monosaccharides are phosphorylated immediately upon entry into cells?
What will be an ideal response?
Monosaccharides are phosphorylated immediately upon entry into cells so that entry into metabolic pathways is possible. Additionally, phosphorylation, to change the structure of glucose, allows the maintenance of a diffusion gradient for simple glucose. Phosphorylation also prevents glucose from leaving the cell.
