Which mechanism contributes to increased glycogen synthase activity during arousal from hibernation in mammals?

💡 Explanation

During arousal from hibernation, shivering thermogenesis requires rapid ATP generation, which is supported by insulin signaling increases cellular glucose uptake which activates glycogen synthase, promoting ATP stability. Therefore insulin stimulation aids ATP generation rather than glucagon increasing glycogen breakdown or decreased cortisol decreasing cellular glucose availability.
