Fig. 4. Original recordings of oxygen concentrations (µmoll–1)
in mitochondrial suspensions from body wall tissue of Arenicola

mmoll–1 ADP, 5 mmoll–1 glutathione (GSH), 1
mmoll–1 NaN3 and 50 µmoll–1
sulfide are marked with arrows. Mitochondrial protein: (A) 0.53·mg
ml–1, (B) 0.48 mg ml–1, (C) 0.35 mg
ml–1.
