← Nature & AnimalsWhich physiological outcome occurs when a hibernating mammal's body temperature activates brown adipose tissue?
A)Non-shivering thermogenesis production increases✓
B)Glycogenolysis rates stimulate rapid locomotion
C)Vasoconstriction reduces overall heat dissipation
D)Basal metabolism triggers increased food consumption
💡 Explanation
When a hibernating mammal’s body temperature rises, brown adipose tissue mitochondrial uncoupling protein-1(UCP1) allows proton leakage across the inner mitochondrial membrane, increasing thermogenesis output. Therefore, non-shivering thermogenesis increases, rather than locomotion, or vasoconstriction which requires active muscle engagement or active restriction in blood supply driven by the hypothalamus.
