Abstract
En 中文
• Mitochondrial H2O2 emission in Drosophila shows distinct site-associated and energetic state thermal sensitivity. • NADH-linked pathways exhibit high ROS production and functional decline at elevated temperatures. • FADH2-linked substrates support respiration at high temperature decoupled from ROS production. • An increased reliance on FADH2-linked substrate oxidation may mitigate ROS production during thermal challenge.
