Decarboxylation process
Citric acid cycle (TCA)
Electron Transport chain
Pyruvate undergo decarboxylation process to produce acetyl CoA and reaction is catalysed by pyruvate decarboxylase. In TCA, acetyl CoA deliver its acetyl group to oxaloacetate which is a four carbon molecule to form citrate, a six carbon molecules with carboxyl groups. In electron transport chain, the reduces FAD and NAD coenzymes release their high high energy electrons and hydrogens to specialized molecules.
