Generation of ATP by Substrate Oxidation

ATP Adenosine triphosphate. Chemical energy generated by substrate oxidations is conserved by formation of high-energy compounds such as adenosine diphosphate (ADP) and adenosine triphosphate (ATP) or compounds containing the thioester bond. 

Fig. 13. Generation of ATP from fuel compx)-nents during respiration. Glucose, fatty acids, and amino acids are oxidized to acetyl CoA, a substrate for the TCA cycle. In the TCA cycle, they are completely oxidized to CO2. As fuels are oxidized, electrons (e ) are transferred to O2 by the electron transport chain, and the energy is used to generate ATP.

Aerobic bacteria (including microaerophilic bacteria) synthesize ATP by coupling oxidation of substrates to the generation of an electrochemical...
