In Tetrahymena, an increase in cAMP level is accompanied by an increased phagocytotic rate, whereas increased sugar uptake is paralleled by a decreased cAMP level. The increase in cAMP level seems decisive with respect to phagocytosis as a basic phenomenon. In the action of epinephrine, some mechanism other than cAMP mediation may be involved. Depending on concentration, 1 hormone may provoke an increase or a decrease in cAMP level, and this triggers the corresponding function.
