Figure. 5. Effect of high concentrations of alpha-glycerophosphate or pyruvate on oscillations in O2 consumption.

Conditions were similar to those described for Fig. 2, except that fura 2 was omitted and 5 mmol/l alpha-glycerophosphate or 1 mmol/l pyruvate was added as indicated. These traces are representative of experiments that were repeated at least three times.
