Which physiological outcome inhibits glycerol synthesis during mammalian hibernation far below freezing?

💡 Explanation

When temperatures drop far below freezing, reduced lipolysis occurs due to enzymatic activity decrease, dramatically halting the supply of fatty acid and glycerol precursors, thus blocking substrate availability. Therefore, lipolysis reduction becomes inhibitory, rather than gluconeogenesis/ autophagy / vasodilation limitations which would less directly impact substrate supply pathways.
