Which outcome results when a hibernating groundhog's muscle glycogen stores are depleted as environmental temperatures suddenly drop?

💡 Explanation

Groundhogs initiate shivering thermogenesis because muscle glycogen depletion limits brown fat activity; shivering produces metabolic heat therefore shivering must drive glucose mobilization rather than brown fat catabolism.
