## Abstract The steady state transport and distribution of chloride between the intracellular and extracellular phases was investigated when the extracellular chloride concentration was varied by isosmotic replacement with nitrate, bromide and acetate. The results of these experiments show that chl

Data from isotopic uptake experiments were used to measure the kinetics of labelling of cellular phosphate, ATP and ADP in the Ehrlich ascites tumor cell. The results show that steady state phosphate exchange flux was 0.333 % 0.052 (S.E.) pmoles per lo' cells per hour at 37", and that the specific a
## Abstract Previous studies have shown that mediated Cl^β^ transport which occurs by at least two processes (Cl^β^βdependent cation cotransport and Cl^β^ selfβexchange) becomes progressively inhibited when extracellular Cl^β^ exceeds about 60 mM (Hoffmann et al., 1979). To account for this type of
Since there was a progressive transition of proliferating cells into a non-proliferating resting state, as well as an increased rate of cell loss in the aging ascites tumor, we examined whether cell loss preferentially affected the nonproliferating or the proliferating cells. The kinetics of cell lo
The effect of extracellular Pi and arsenate on Pi-transport in Ehrlich ascites tumor cells has been studied. Pi-transport can be described by Michaelis-Menten kinetics; the maximal flux equal to 44 mmoles (kg cell water)-' hour-' and K m equal to 3.3 X 1 0 -4 M. Arsenate is a competitive inhibitor o
