In glycolysis and enzyme one molecule of glucose is broken into two molecules of pyruvate.

2.Pyruvate

The two molecules of pyruvate that were produced in glycolysis are oxidized in the mitochondria.

CO2,NADA and a acetyl group are produced

3.Krebs Cycle

The Acetyl molecules from the pyruvate oxidation in the matrix and go into a metabolic cycle where the Acetyl group is oxidized to CO2 .

4.Electron Transport

1.Glycolysis

High energy ATP and NADH are synthesized

High energy ATP and NADH are synthesized

This allows ATP,NADH and FADH2 to be synthesized

The NADH and FADH2 that were produced the glycolysis, P.O, and and Krebs are oxidized. The high energy electrons and hydrogens are passed from one oxidizing agent to the other till they transferred to O2

All the free energy released is used to synthesis large amounts of ATP
