All the free energy released is used to synthesis large amounts of ATP
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
This allows ATP,NADH and FADH2 to be synthesized
High energy ATP and NADH are synthesized
1.Glycolysis
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
