... were therefore able to estimate its diffusion coefficient and permeability coefficient (6 × 10 −3 cms −1 ). This ammonia diffusion was shown to be modified according to the external proton availability. For sodium absorption, significant changes were caused by indirect modifications of intracellular pH...

...Hans-Otto Pörtner ABSTRACT The quantitative influence of anaerobic metabolism on acid-base status and on acid-base regulation is investigated in Sipunculus nudus L. Proton generation by metabolism is calculated from theoretical predictions. The quantitative comparison of metabolic protons with non...
