Enzymatic regulation of seasonal glycogen cycling in the freeze-tolerant wood frog, Rana sylvatica

Liver glycogen is an important energy store in vertebrates, and in the freeze-tolerant wood frog, Rana sylvatica , this carbohydrate also serves as a major source of the cryoprotectant glucose. We investigated how variation in the levels of the catalytic subunit of protein kinase A (PKAc), glycogen...
