Circadian rhythmicity in phosphorylase activity and glycogen content in the heart muscle of the scorpion, Heteromentrus fulvipes, C.L. Koch.
Maximal activity levels of phosphorylase A and AB at 20.00 h alternate with minimal levels at 08.00 h of the day, while the glycogen content exhibited a reverse trend in the heart of the scorpion, Heterometrus fulvipes.
