Which shift in metabolic activity occurs during mammal hibernation's torpor phase?

💡 Explanation

During torpor, hypothermia minimizes energy waste, so fatty acid beta-oxidation happens because brown fat mitochondria sustain heat mostly, producing ATP still. Therefore elevated fat oxidation happens in torpor, rather than glycolysis, phosphorylation changes, or biosynthesis changes, needing constant higher energy needs.
