Because mitochondria play a fundamental role in the transduction of energy from food into ATP. The coupling between nutriment oxidation and ATP production (P/O ratio) can vary among individuals and in response to a number of environmental parameters, such as diet and temperature. As the mitochondrial coupling affects the efficiency of cellular energy production, its variability may have significant consequences for animal performance. We explore the advantage and cost of such variability in response to food shortage in birds or in relation with growth rate in frogs.
