AbstractThe latency of both acid phosphatase and ribonuclease was studied throughout the growth cycle of the ciliate protozoanTetrahymena pyriformisand was found to be remarkably low in cells in the logarithmic phase of growth. The latency increased progressively throughout the log phase until it reached a maximum just after the cells had entered the stationary phase.The specific activity of acid phosphatase remained constant throughout the whole of the growth cycle while that of ribonuclease decreased as the cells began to leave log phase.The possibility is discussed that all rapidly dividing cells have a high proportion of their acid hydrolases outside the lysosomes and that these free hydrolases may have a function in cell division.
