Mean Q₁₀ values for state 2 respiration rates of BAT mitochondria isolated from torpid or interbout euthermic (IBE) 13-lined ground squirrels measured in vitro at 10°C and 37°C

	Q10
Oxidative Substrate	IBE	Torpor
Pyruvate	2.40 ± 0.06	1.38 ± 0.17*
Octanoyl carnitine	2.30 ± 0.15	1.42 ± 0.13*

Values are means ± SE and derived from mitochondrial respiration rates from individual animals and measured at both temperatures, plotted in Fig. 5.

^*Significantly lower values (2-tailed Student's t-test, P < 0.05).
