Figure 5. O₂ consumption, respiratory quotient and percentage active time of G0S2^−/− mice vs. G0S2^+/+ mice. (A–C) Time course of (A) O₂ consumption, (B) respiratory quotient, and (C) percentage active time of G0S2^+/+ vs. G0S2^−/− male mice fed a 10% fat diet (left panel) or a 45% fat diet (right panel) during 24 h with access to food and water ad libitum (n = 12). Data are presented as mean ± SE. The symbol * depicts statistical significance as P < 0.05.
