Ratios based on mitochondrial respirational flux in N. celidotus at 15°C, 17.5°C, 20°C, 25°C, 27.5°C, 30°C and 32.5°C. OXP-I, II/Leak-I, II (also termed RCR 2, [50]) ratio is a simple proxy of inner membrane permeability.

The Leak-I, II/ETS (termed flux control ratio, FCR) provides a measure of ETS capacity relative to the leak respiration state when phosphorylation is inhibited by atractyloside. CCO/OXP-I, II and CCO/ETS are measures of the capacity of cytochrome c oxidase (CCO) relative to maximum phosphorylation (OXP-I, II) or the ETS respectively.Values are means ± S.E.M. (N = 8 at each temperature).Means with the same letter of the same case are not significantly different from one another (p≤0.05).
