Why are monosaccharides immediately phosphorylated upon entry into cells?
Wiki User
∙ 12y ago
One example of modified monosaccharides are the phosphorylated sugars. An important phosphorylated sugar is glucose 6-phosphate, which is a glucose phosphorylated on carbon 6. The significance of this molecule is that it provides energy in certain metabolic pathways, and it can be converted and stored as glycogen when blood glucose levels are high. If blood glucose levels are low, glucose 6-phosphate can be converted back into glucose to enter the bloodstream once again. A unique property of glucose 6-phosphate is that once glucose is phosphorylated, the sugar possesses a negative charge. This prevents the molecule from leaving the lipid-bilayer membranes. This allows the cell to easily access the modified sugar to provide energy for metabolic pathways such as glycolysis, or convert it to glycogen as storage.

Why only one sperm cell can fertilized an ovum?
Ovum has a layer of zona pellucida around itself. When a sperm enters the ovum, the cortical granules present in the ovum, causes the thickening of the zona pellucida. This prevents the entry of other sperms in the ovum and only one sperm is able to fertilize the egg.
