TCA cycle function

The TCA cycle functions as a major route for the synthesis and oxidation of most amino acids and is the primary route through which amino acid carbon flows in the synthesis of other small molecules (Figure... 

The TCA cycle functions for both the oxidation and the production of reducing equivalents from a variety of metabolites such as carbohydrates, amino acids, and fatty acids. In the mitochondria fatty acids undergo successive removal of two carbon units in the form of acetyl-CoA, which is converted in the TCA cycle to CO2 and reducing equivalents found in NADH and FADH2. The latter two substances are then fed into the electron transport chain. The formation of each acetyl-CoA molecule... 

The TCA-cycle functions to convert pyruvic and lactic acids, the end products of anaerobic glycolysis (EMP), to CO2 and H2O. It also is a common channel for the ultimate oxidation of fatty acids and the carbon skeletons of many amino acids. The overall reaction is ...
