ATP levels normalized to total ATP synthesis given by succinate respiration. Data from Fig. EV 3B. Succinate data shown for comparison after normalization. Two-way ANOVA with Sidak's test for multiple comparisons, *p = 0.0011, +ATR succinate vs +ATR light p = 0.5680, n = 3,7,3,7, biological replicates for each bar from left to right. Some individual points overlap. Data show mean + SEM.
