Fig. 4 — Effects of metabolic poisons on light-induced changes of respiratory O₂ uptake rates in S. ruber. A. 1, light-induced changes of respiration at 2 mW cm^-2 of white light; 2, shift of dark level and light-induced changes of respiration in the cells after addition of 10 mM KCN; 3, after subsequent addition of 10 mM of o-phenanthroline. B. 1, light-induced changes of respiration in control cells; 2, in the cells pretreated for 1 h with 0.5 mM DCCD; 3, and after subsequent addition of 1 μM CCCP. The breaks in the traces A and B correspond to ∼20-30 min of equilibration of O₂ concentration in the microchamber.
