Which physiological response reduces energy expenditure during induced torpor in small mammals?

💡 Explanation

During induced torpor, conservation of energy occurs via suppression of unnecessary energy expenditure, thus shivering thermogenesis is reduced because it generates heat. Therefore a decrease in shivering reduces energy consumption, as opposed to brown fat upregulation, increased heart rate variability, or basal metabolic rate elevation, the latter of which increases energy use.
