Pyruvate + NAD+ + CoA → Acetyl COA NAIDHI + H + CO₂ This is the overall reaction for the pathway of Glycolysis Oxidative decarboxylation of pyruvate Fatty acid oxidation Ellectron transport Oxidative phosphorylation TCA or citric acid cycle

The metabolic function of the pentose phosphate pathway is: act as a source of ADP biosynthesis provide intermediates for the citric acid cycle. generate NADPH and pentoses for the biosynthesis of fatty acids and nucleic acids. O participate in oxidation-reduction reactions during the formation of H2O.
