In plants, mitochondria also possess additional alternative electron transport pathways, including the alternative oxidase (AOX) pathway, which transfers electrons from ubiquinol to O\n                    <jats:sub>2<\/jats:sub>\n                    , bypassing the cytochrome\u2010dependent electron transport chain.

This suggests that the cytochrome pathway can compensate for AOX loss and effectively support the consumption of reducing power produced by photosynthesis even under stressful conditions. Although photosynthetically active cells can produce ATP in chloroplasts under illumination independently of mitochondrial electron transport, respiration is shown to be essential for the conversion of reducing power into ATP for distribution throughout the cell. Simultaneous inactivation of AOX and CIII was lethal, indicating that AOX and the complementary cytochrome pathway contribute to the essential role of mitochondrial respiration in the redox and energy
