Which metabolic outcome occurs during extended winter hibernation when skeletal muscle stops shivering thermogenesis?

💡 Explanation

When skeletal muscles stop shivering thermogenesis during extended hibernation, the body shifts to non-shivering mechanisms such as activating brown fat, which uses uncoupling protein 1 (UCP1) to generate heat without ATP production. Therefore, dependence on brown fat metabolism increases, rather than glycogenolysis, urea recycling, or enhanced gluconeogenesis, which are less significant in hibernation.
