Schematic representation of the cellular mechanisms by which insulin and -adrenergic stimulation promote potassium uptake by extrarenal tissues. Insulin binding to its receptor results in hyperpo- larization of cell membranes (1), which facilitates potassium uptake. After binding to its receptor, insulin also activates Na+-K+-ATPase pumps, resulting in cellular uptake of potassium (2). The second messenger that mediates this effect has not yet been identified. Catecholamines stimulate cellular potassium uptake via the 2 adren- ergic receptor ( 2R). The generation of cyclic adenosine monophos- phate (3 , 5 cAM P) activates Na+-K+-ATPase pumps (3), causing an influx of potassium in exchange for sodium. By inhibiting the degradation of cyclic AM P, theophylline potentiates catecholamine- stimulated potassium uptake, resulting in hypokalemia (4). M ore than half of filtered potassium is passively reabsorbed by the end of the proxim al convolted tubule (PCT). The m ajor site of active potassi- um reabsorption is the thick ascending lim b of the loop of H enle (TAL), so that, by the end of the distal convoluted tubule (DCT), only 10% to 15% of filtered potassium rem ains in the tubule lum en. Potassium is secreted m ainly by the principal cells of the cortical collecting duct (CCD) and outer m edullary collecting duct (O M CD). Potassium reabsorption occurs via the intercalated cells of the m edullary collecting duct (M CD). Urinary potassium repre- sents the difference between potassium secreted and potassium reabsorbed. During states of total body potassium depletion, potassium reabsorption is enhanced. Reabsorbed potassium initial- ly enters the m edullary interstitium , but then it is secreted into the pars recta (PR) and descending lim b of the loop of H enle (TDL). The physiologic role of m edullary potassium recycling m ay be to m inim ize potassium “backleak” out of the collecting tubule lum en or to enhance renal potassium secretion during states of excess total body potassium. The percentage of filtered potassium rem aining in the tubule lum en is indicated in the corresponding nephron segm ent.
