The straight line suggests that the rate of uptake is limited by an absorptive step at high concentrations. The process of accumulation of radioactivity in the form TABLE I Uptake of amino acids by suspensions of 2 X 106 cells per nil. Per cent of substrate accumulated after 30 minutes is shown at substrate concentrations ranging from 1 X 10~6 to 2 X 10~7 molar % Accumulation Arginine >95 Glutamic acid 65 Glvcine >95 Phenylalanine 50 Valine 90 Glucose 4.
