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

To determine the extent of coupling between the transport of potassium and the transport of amino acids by the Ehrlich mouse ascites tumor cell, we have investigated the effect of pyridoxal on potassium fluxes. We have chosen a low Concentration of pyridoxal (1 mM) known to increase the cell to medi
## Abstract The addition of glucose to ELD and ELT/B1 mouse ascites tumor cell suspensions caused a 2.3โfold increase in the phosphorylation state ratio, (ATP)/(ADP)(Pi), because of a decrease in the intracellular Pi concentration. The addition of glucose to these cell suspensions has been reported
