Fig. 2. Rates of oxygen consumption in rat heart SMPs after partial depletion of CoQ.

Fig. 2

Freeze-dried SMPs were depleted of their native CoQ homologues by repeated pentane extractions. After each extraction procedure, the rate of oxygen consumption was measured polarographically with a Clark-type electrode using 7 mM succinate as a substrate. The inset shows the SMP CoQ content remaining after each extraction procedure with pentane. The (remaining) CoQ content was determined in hexane:ethanol extracts by HPLC. Data are mean ± S.E. of three independent experiments. S.E. is not shown in the inset.
