Abstract
The dynamics of uptake of labeled amino acids by rhythmically functioning acinar cells of the rat parotid gland was studied. The amino-acid reserves in the parotid, gland cells fluctuate regularly. However, the period of intake of the amino acids into the cell, unlike the periods of fluctuation, of the intensity of protein synthesis, is independent of the animals' training program: In all the experiments the periods were the same and were equal to the endogenous period of the change in intensity of protein synthesis in the cells. The regular fluctuation of the total amino-acid reserves of the cell cannot be regarded as a direct regulator of synthesis of the protein assimilated by the cells during the experiment.
