[Dynamic changes in the pH and potassium concentration in a suspension of ascitic tumor cells under glucose load].
A single addition of glucose to 10% (6 v/v) suspension of the Ehrlich ascite tumor cells results in biphasic changes of pH and potassium ion concentration in the extracellular medium during 120 minutes. Phases of pH and potassium changing do not coincide. Increasing glucose amount from 100 to 400 mumol/10 ml suspension causes no marked modification of ion dynamics. Possible mechanisms of the above phenomena and their relation to cell power are discussed.
