Enzymatic activity of the mitochondrial complexes for liver and skeletal muscle of age-matched rats that did not reproduce (NR), and rats that did not (PP) or did (PL) suckle their young for 21 days postpartum. Data include (a) complex I, (b) complex II, (c) complex III, and (d) complex IV activity in the liver. In addition, data include (e) complex I, (f) complex II, (g) complex III, and (h) complex IV activity in skeletal muscle. Complex activity data are normalized to citrate synthase (CS). Data shown are mean ± SD. * indicates different from NR (p < 0.05), and # indicates different from PP (p < 0.05)
