Asymmetry of Membrane Functions in Transporting Cells,ion, for extracting nutrients from the surrounding medium, and for excreting metabolic end products. In addition, as cells become organized into structures of greater complexity, they must assume progressively more specialized functions. The function to be considered here is that of transport across

Recent Developments in Renal Handling of Glutamine and Ammonia,echniques it has not been generally possible to establish the relationship between transport and metabolism, and transport of materials has often been studied without reference to the intracellular metabolic events which ensue. No such dissociation of thought has occurred in considering the renal ha

Renal Transport of Amino Acids and Oligopeptides,des more than merely absorption of filtered amino acids from the tubular fluid. Like the cells of many other organs the tubule cells take up amino acids also directly from the (peritubular) blood [3, 34, 89, 98; review: 113] (see top of Fig. 1). Only the cells of the early proximal tubule may be pro

Renal Transport of Urea,bians and in mammals. The movements of urea between different compartments of body fluids are usually described by three dogmatic statements: (1) Biological membranes are generally “freely” permeable to urea or, in other words, are practically as permeable to urea as to water. (2) The main exception

Transport of D-Glucose in the Mammalian Kidney,ure is reviewed comprehensively in the Handbook of Physiology, Section 8, Chapter 19 [85]. Special emphasis has been given to the quantitative findings rather than to the presentation of theoretical considerations. Certainly, as consequence of the necessary shortness, some important contributions we

Characteristics of p-Aminohippurate Transport in the Mammalian Kidney,erved that when administered parenterally, phenol red is rapidly and quantitatively excreted in the urine. Since some 60% of this substance is bound to plasma albumin and, hence, cannot be filtered through the glomerular capillaries, the authors concluded that the high rate of excretion of phenol re
