Reactants Products and Equation of Glycolysis Process

The reactants products and equation of glycolysis can be described in a short sentence. But to understand the net equation of the glycolysis, we must look at all the 10 steps of glycolysis.

Reactants Products and Equation Of Glycolysis Process in Each of  10 Steps:


1. Glucose + ATP                       ←→        Glucose 6-phosphate + ADP.

2. Glucose 6-phosphate                ←→             Fructose 6-phosphate.

3. Fructose 6-phosphate + ATP           →   Fructose 1,6-bisphosphate + ADP.

4. Fructose 1,6-bisphosphate                ←→       Dihydroxyacetone phosphate  + Glyceraldehyde 3-phosphate.

5. Dihydroxyacetone phosphate           ←→           Glyceraldehyde 3-phosphate.

6.Glyceraldehyde 3-phosphate + Pi + NAD         ←→   1,3-Bisphosphoglycerate + NADH + H.

7. 1,3-Bisphosphoglycerate + ADP           ←→    3-phosphoglycerate + 2 ATP.

8. 3-Phosphoglycerate                    ←→        2-phosphoglycerate.

9. 2-Phosphoglycerate                    ←→        phosphoenolpyruvate + H2O.

10. Phosphoenolpyruvate + ADP     →        2 pyruvate + 2 ATP.

Net Equation of Glycolysis Process:

So Net Equation of Glycolysis Process is

Glucose + 2NAD + 2ADP + 2Pi  →   2 pyruvate + 2NADH + 2H + 2ATP + 2H2O.
