Which metabolic consequence results when a hibernating marmot experiences a sudden, involuntary shivering episode?

💡 Explanation

When a hibernating marmot shivers, muscle contraction thermogenesis occurs because muscles rapidly hydrolyze ATP to generate heat, triggering glycogenolysis in the liver to replenish energy stores to fuel muscle activity. Therefore, rapid glycogen depletion results, rather than increased brown fat activity, decreased ATP production, or suppressed vasodilation, which contradict normal shivering physiology.
