Figure. 6. Effect of fructose-2,6-P2 (A) or ADP (B) on oscillations in O2 consumption.
Conditions were similar to those described for Fig. 2, except that fura 2 was omitted and 100 μmol/l fructose-2,6-P2 (A) or 1 mmol/l ADP (B) was added at the time indicated by the arrow. These traces are representative of experiments that were repeated at least three times.
