← Nature & AnimalsWhich physiological response decreases upon prolonged deep hibernation?
A)Ventricular fibrillation vulnerability rises
B)Mitochondrial uncoupling process decreases✓
C)Brown fat catabolism rate elevates
D)Peripheral vasodilation magnitude intensifies
💡 Explanation
Mitochondrial uncoupling decreases in deep hibernation because metabolic rate dramatically slows using torpor, thereby reducing heat produced within brown fat tissue rather than increasing thermogenesis; therefore less non-shivering thermogenesis occurs, rather than fibrillation risk or fat activation.
