Which outcome occurs when prolonged cold exposure depletes glycogen?

💡 Explanation

Ineffective non-shivering thermogenesis results because the depletion of liver glycogen inhibits cellular respiration pathways fueling the uncoupling protein 1 channel in the mitochondria, which generates heat rather than ATP; therefore, shivering is stimulated prior to depletion rather than afterward.
