Fig. 3. (A) O2, (B) {Sigma}H2S and (C) {Sigma}CO2 uptake rates (µmol g-1 h-1); (D) proton elimination rates (µequivalents g-1 h-1), by Riftia pachyptila as a function of O2 concentration (mmol l-1). pH was maintained at 6.1 and all other substrates were held at `typical' concentrations (see Materials and methods). All rates are expressed in terms of wet mass.
