Which process maintains core temperature homeostasis during mammal hibernation?

💡 Explanation

During hibernation, animals lower metabolic rate; non-shivering thermogenesis in brown fat generates heat through uncoupling protein-1 (UCP1), disrupting the proton gradient in mitochondria. Therefore heat production maintains core temperature and prevents hypothermia rather than panting, counter-current exchange,or decreasing signaling which further reduces heat.
