Correlations between glucose-inhibition and control parameters of alpha-glucosidase kinetics in Apis mellifica haemolymph (Hymenoptera: Insecta).

Kinetics studies of haemolymph alpha-glucosidase inhibition by D. glucose led to general correlations between inhibition and control parameters, all over the honeybee development. Maximum velocities are not affected by the inhibition, while affinity constants are always significantly increased, and Hill coefficients tend to decrease, especially in for-aging adults and in prenymphs. In this later case, the 'n-type' effect tends to break the manifestation of the 'K-type' mechanism.
