1. Glucose
2. Phosphorylated glucose
3. G3P (two of them).
Glycolysis refers to the process of breaking down glucose molecules into two three-carbon compounds generating energy.
In the first step, the glucose molecule is activated by adding a phosphate group, producing glucose-6-phosphate. In other terms, glucose is being phosphorylated. It is then converted into fructose-6-phosphate and another phosphate is being added. It produces fructose diphosphate and splits into two 3-carbon molecules. The next step is converting the (DHAP) to glyceraldehyde-3-phosphate resulting in two G-3-P's.
