Glycolysis

The first step as soon as the glucose enters the cell is that it undergoes immediate phosphorylation. So that it cannot diffuse out of the cell. This is because, on phosphorylation, the glucose becomes polar and hence cannot flow across the plasma membrane passively.

This step functions at ...

Once glucose is converted into glucose 6-phosphate, it is then isomerized into fructose 6-phosphate. The basic reason behind this conversion is that the addition of one more phosphate into glucose is not possible, due to its cyclic structure. Where only one carbon atom is present outside of the r...

The phosphoglyceride hence obtained undergoes partial oxidation. It reacts with an inorganic phosphate and results in the formation of 1,3-bisphosphoglyceric acid along with the synthesis of an NADH+H+.
