Mechanisms of Absorption, Transport, Accumulation, and Secretion of Ions

this area one frequently proceeds without knowledge of the vast already existing experimental material which must be adequately evaluated before it may be described as real progress. Conway (8) has treated the general problem of a redox pump for ions from a thermodynamic point of view, but his scheme shows no salient features which may be distinguished from the theory of anion respiration. The author presented a review of the anion respiration to the symposium on active transport of ions in Bangor, England in 1952 (12 ). The substance of the present article is much the same, but the discussion of the more impor­ tant literature has been extended.
