Which process dictates an awakening grizzly bear's body temperature?

💡 Explanation

Non-shivering thermogenesis dictates core temperature because brown fat mitochondria contain thermogenin uncoupling oxidative phosphorylation, therefore, less ATP is produced, rather than shivering which increases mechanical activity, not core temperature directly.
