Which outcome occurs when a hibernating marmot awakens prematurely due to an unexpected warm spell, disrupting fat metabolism?

💡 Explanation

When the marmot awakens, premature heat production requires vasodilation to dissipate heat, accelerating metabolism of limited brown fat stores because core temperature increases. Therefore vasodilation results in rapid energy depletion, rather than glycogenolysis, upregulation or ketogenesis which have converse effects on thermoregulation.
