Brazier sail_bad@yahoo.com 1 Bendigo Kangan Institute, Bendigo, Victoria, Australia To study the connection between ammoniagenesis, gluconeogenesis and calcium exchange in kidney tubules, isolated kidney tubules were incubated in media with pH 5 and pH 7.2 and the exflux of calcium, ammonia production and cellular ATP levels was measure after a constant time period. Results indicate that calcium transport was reduced in low pH and by ammoniagenesis and increased my acetate and pyruvate and insulin inclusions. Results support the hypothesis that the calcium is controlled by ATP availability and that insulin can affect calcium transport by controlling ATP availability. http://pubs.sciepub.com/ajfn/4/4/2/ajfn-4-4-2.pdf ammoniagenesis gluconeogenesis calcium exchange hypercalciuri
