Which mechanism causes reduced oxygen consumption when entering hibernation?

💡 Explanation

When entering hibernation, metabolic rate slows via reduced mitochondrial proton leak because UCP-1 uncouples ATP production, decreasing energy expenditure and oxygen demand. Therefore decreased proton leak results, rather than RBC increase, glycogenolysis, or vasodilation, which alter respiratory capacity or metabolic substrate availability in different ways.
