A comparison of the effects of substrate mixtures on the succinate
supported state 3 respiration and state 4 generation of
H2O2 by non-BSA-brain mitochondria. Incubation
conditions were as in Figs. 4
and 5. All experiments were
made on the same batch of mitochondria. Data were normalized to the succinate
alone, taken as 100%. S, succinate (5 mm); P,
pyruvate (2.5 mm); G, glutamate (5 mm);
M, malate (2 mm).
