Conductances within the electron transport chain. A: Conductance of electron flux between NADH and cytochrome c1 with and without calcium. B: Conductance of electron flux between cytochromes c1 and c with and without calcium. C: Conductance of electron flux between cytochromes c and a607 with and without calcium. D: Conductance of electron flux between cytochrome a607 and O2 with and without calcium. Filled squares – calcium, open diamonds – no calcium. Trendlines are included for relationships with R2 values above 0.8. n = 4. Slopes, regression analyses, and the resultant p-values are reported in Table 2 for A-D as LCI+III, Lc1c, LCIVa, and LCIVb, respectively.
