Correlations between glucose-inhibition and control parameters of α-glucosidase kinetics inApis mellifica haemolymph (Hymenoptera: Insecta)

Summary

Kinetics studies of haemolymph α-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 foraging adults and in prenymphs. In this later case, the ‘n-type’ effect tends to break the manifestation of the ‘K-type’ mechanism.
