Biology OpenElisa Thoral et al (Lund University, Lund, Sweden) show that in wild great tits, unlike in mammals, there is no correlation between resting metabolic rate and mitochondrial respiration.
“An ancillary goal was also to investigate the relationship between blood mitochondrial respiration and blood cell count.”
The relationship between mitochondrial respiration, resting metabolic rate and blood cell count in great tits
Summary: Our results show that the relationship between resting metabolic rate and blood mitochondrial metabolism depends on the level of cellular permeabilization as well as the level of activation of the electron transport chain. No relationship was detected between blood mitochondrial respiration and blood cell count in our conditions.
