Activity of electron carrying complexes, and the Kreb's cycle enzyme citrate synthase. Data were acquired using untreated skeletal muscle mitochondria thawed only once, except for complex I activity which requires three cycles of freeze‐thaw (Spinazzi et al., 2011). Assays were conducted at the species’ normal body temperature and normalized to mg of protein (a), or to the activity of citrate synthase (b). CI = complex I, CII = complex II, CIV = complex IV, CS = citrate synthase, NMR = naked mole‐rat. In panel a, for mouse, n = 15, 16, 15, 10, 11 from left to right, for NMR, n = 8 except for CI, where n = 6. In panel b, for mouse n = 10 (except for CI, n = 11), for NMR, n = 8 (except for CI, n = 6). Other details of statistics are as in Figure 2
