... in the pGL3-Per2-luc vector are already flanked by BamHI cutting sites, the pGL3-Per2-luc vector was directly digested with BamHI for Per2:luciferase sequence extraction. The leak state is defined as the mitochondrial respiration in the presence of fuel substrates and in the absence of ADP. It reflects...

... production originating from mitochondrial respiration. Within this framework, FAO has a much larger FADH 2 /NADH ratio than glucose breakdown. Further, the longer the fatty acid, the higher the FADH 2 /NADH ratio, and the higher the level of ROS production, as complex I, known as a major source of ROS...

...) and swimming performance [critical swimming speed ( U crit ) and cost of transport (COT)] were assessed. In addition, enzyme activities [citrate synthase (CS), cytochrome c oxidase (COX) and lactate dehydrogenase (LDH)] and mitochondrial respiration were examined in red muscle fibres. We found that acclimation...

... thermal tolerance. We acclimated Atlantic salmon to 12 and 20°C (for >2 months), and investigated the effects of acute and chronic warming on cardiac mitochondrial respiration and reactive oxygen species (ROS) production (release rate) using high-resolution fluorespirometry. Further, we compared...
