Mitochondrial function in the skeletal muscles of young and old rats. A Mitochondrial O2 respiration in the (left) soleus and (right) white gastrocnemius muscle (WG, n = 9). B Mitochondrial H2O2 emission rate in the (left) soleus and (right) white gastrocnemius muscle (WG, n = 9). C Mitochondrial calcium retention capacity in the soleus and white gastrocnemius muscle (n = 9). **p < 0.01, ***p < 0.001 by unpaired t-test. GM, glutamate + malate; ADP, adenosine diphosphate; Succ, succinate; GMS, GM + succinate; GMSG3P, GMS + glycerol 3 phosphate
