Formulas

Glycolysis and Pyruvate Formation

Glucose + ATP --hexokinase/Mg++--> Glucose-6-phosphate + ADP

Fructose-6-phosphate + ATP --phosphofructokinase/Mg++--> Fructose-1,6-diphosphate + ADP

Aerobic Oxidation of Pyruvic Acid and Krebs Cycle

Pyruvic acid + CoA + NAD+ --pyruvic dehydrogenase multienzyme complex (TPP, lipoic acid, Mg++)--> Acetyl CoA + CO2 + NADH + H+

Acetyl CoA + Oxaloacetic acid + H2O --citrate synthase--> Citric acid + CoA

Succinic acid + FAD --succinic dehydrogenase--> Fumaric acid + FADH2

Electron Transport System and Oxidative Phosphorylation

For every pair of electrons passed along this system, three ATP are formed.

An electron pair originating from NADH yields three molecules of ATP, while the one originating from FADH2 yields only two molecules of ATP as it is f
