Figure S1 from Linking Performance to Powerhouse: Mitochondria Aerobic Metabolism in Blood Cells Reflects Flight Endurance of House Sparrows (Passer domesticus)

Typical oxygen consumption trace obtained during our study using an Oroboros O2k depicting key mitochondrial respiration phases and measurements after the addition of blood cells (BC). a) Baseline respiration. b) Substrate-stimulated respiration after pyruvate addition (P). c) OXPHOS capacity (ATP-linked respiration). d) Leak respiration after oligomycin (OMY, ATP synthase inhibitor) addition. e) Electron Transport System (ETS) capacity following CCCP (uncoupler, U) titration. f) Non-mitochondrial respiration after antimycin A (AMA, Complex III inhibitor) addition, used for background subtraction.
