rylation (reduced nicotinamide adenine dinucle- otide [NADH] /H1reduced avin adenine dinucleotide [FADH 2]adenosine triphosphate [ATP]). Oxygen ( is consumed, whereas carbon dioxide (CO , some heat, and energy carriers are released. The process can be described by the simple equation: C6H1O6/H1O 2/H1 ADP 6C 2/H1H 2O/H1 ATP ( Adenosine triphosphate (ATP) is the main energy carrier and is used in numerous cell functions. reduction in respiration will result in decreased ATP production, since the vital role of respiration is the generation of ATP (energy). Consequently, less energy is available for processes associated with ripening, resulting in quality changes. The con-trol of respiration by environmental factors such as temperature and gas composition isdiscussed in Sec. 2.4. Accurate estimations of energy production and consumption are essential for under- standing postharvest applications, such as altered gas conditions. On the energy production side, for instance, the belief that 3 ATP are released per glucose molecule is still under debate, with 3 or lower sometimes being reported. The contributions of alternative and residual respiration to 2consumption are important for the estimation of energy pro- duction (see Sec. 2.1.). For energy use, it is important to know whether or not pro-cesses inuencing the main quality attributes require lot of energy, and if extremetreatments will cause an energy status that is unable to cover maintenance needs (seeSec. 2.. 2.1.1 Alternative and Residual Respiration substantial part of the 2consumption might not be used for cytochrome respiration, but for alternative respiration or other 2-consuming processes (residual respiration). Al- ternative respiration is an alternative to the cytochrome pathway of electron transport toO 2. It branches from the main respiratory chain at ubiquinone, and results in CO 2and heat production but not ATP production. Alternative respiration can take place when cyto- chrome respirat
