Enzymatic complex activity of isolated mitochondria for age-matched rats that did not reproduce (NR), and rats that did not (NL) or did (L) suckle their young. 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 (n = 6–8 per group). No statistical differences detected (p > 0.05).
